Hurricane Harvey

star gazer · 25-08-2017 10:42am #1

Hurricane Harvey looks set to be the first Major Hurricane to make landfall in the United States in over a decade and one of the most worrying aspects of it is the forecast for Harvey not to move very far for days after making that landfall, meaning a lot of rain will fall over a large section of the Texas coastal area for an extended period. 400mm to 650mm of rain could fall in a large area of the Texas coast and up to 900mm in isolated parts with storm surges of 1 to 3.5 meters. At the moment Minimum Central Pressure is 967mb with max sustained winds of 165km/h 105mph making it a Category two Hurricane. It is due to strengthen to a Category 3 Major Hurricane today and make landfall some time late Friday local time. Houston is forecast to get huge rainfall with actual landfall likely to be made somewhere near Corpus Christi.

A report from the weather channel warning that it's the water (storm surge and rainfall flooding) that causes the most fatalities in these natural disasters:
https://twitter.com/weatherchannel/status/900838671775133696
The first rain bands are affecting land already. Donegal saw what can happen with a large amount of rain in a short space of time, Such a large amount of rain over an extended period will be an enormous test of communities and of their emergency response services.

Strong words from the NHC, looks like this could be devastating;

At 1000 AM CDT (1500 UTC), the eye of Hurricane Harvey was located
by an Air Force Reserve Hurricane Hunter aircraft and NOAA Doppler
radar near latitude 26.7 North, longitude 96.0 West. Harvey is
moving toward the northwest near 10 mph (17 km/h), but its forward
speed is expected to decrease significantly during the next couple
of days. On the forecast track, Harvey will make landfall on the
middle Texas coast tonight or early Saturday. Harvey is then likely
to meander near or just inland of the middle Texas coast through the
weekend.

Maximum sustained winds are near 110 mph (175 km/h) with higher
gusts. Some strengthening is possible, and Harvey is forecast to
become a major hurricane before it reaches the middle Texas coast.

Hurricane-force winds extend outward up to 35 miles (55 km) from the
center, and tropical-storm-force winds extend outward up to 140
miles (220 km). A buoy located about 40 miles east of South Padre
Island recently reported sustained winds of 42 mph (68 km/h) and a
gust to 54 mph (86 km/h).

The minimum central pressure based on data from the Air Force plane
is 947 mb (27.97 inches).

HAZARDS AFFECTING LAND
RAINFALL: Harvey is expected to produce total rain accumulations
of 15 to 25 inches and isolated maximum amounts of 35 inches over
the middle and upper Texas coast through next Wednesday. During
the same time period Harvey is expected to produce total rain
accumulations of 5 to 15 inches in far south Texas and the Texas
Hill Country over through southwest and central Louisiana. Rainfall
of this magnitude will cause catastrophic and life-threatening
flooding.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide...

N Entrance Padre Island Natl Seashore to Sargent...6 to 12 ft
Sargent to Jamaica Beach...5 to 8 ft
Port Mansfield to N Entrance Padre Island Natl Seashore...5 to 7 ft
Jamaica Beach to High Island...2 to 4 ft
Mouth of the Rio Grande to Port Mansfield...2 to 4 ft
High Island to Morgan City...1 to 3 ft

The deepest water will occur along the immediate coast near and to
the northeast of the landfall location, where the surge will be
accompanied by large and destructive waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle, and
can vary greatly over short distances. For information specific to
your area, please see products issued by your local National Weather
Service forecast office.

WIND: All last-minute preparations should be rushed to completion
since tropical storm conditions are likely just beginning in
portions of the hurricane and tropical storm warning areas.
Hurricane conditions are likely to begin within the hurricane
warning area later today or tonight. Tropical storm conditions are
likely to persist along portions of the coast through at least
Sunday.

SURF: Swells generated by Harvey are affecting the Texas,
Louisiana, and northeast Mexico coasts. These swells are likely to
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.

TORNADOES: A few tornadoes are possible later today through
Saturday near the middle and upper Texas coast.

The hurricane has strengthened to a category 3 one. And having watched the mayor of corpus Christi earlier and the governor of Texas, it's clear they are worried.

star gazer · 25-08-2017 8:31pm

"Catastrophic flooding" seems the best quick sum up of this, though there are other dangers.
It's been upgraded to a Major Hurricane, Category 3, 195km/h, 120mph, min central pressure down to 943mb.
The storm surge has begun near Corpus Christy. Potential storm surge map.
Tornado warnings going out.
I haven't seen similar Hurricanes talked about that lingered as long as Harvey is forecast to, does anyone know of any like that historicaly?

Doesn't a European model have it stalling, then coming back out into the Gulf and restrengthening before a final move NE?

Rock Lesnar · 25-08-2017 8:36pm

Watching CNN at the minute, its completely mad that people would still stay and try stick it out considering the warnings about how bad its gonna be

Upto to 36 and possibly more inches of Rain forecast :eek:

Akrasia · 25-08-2017 8:45pm

I heard some officials telling people to leave, that they should go visit friends or family, or just head to higher ground.

It's possible there are lots of people who don't have anywhere to go and no way of getting there.

I hope they have shelters and transport for people to get out of the path of this storm. They probably do for the mandatory evacuations, but what about those places where it's voluntary but strongly advised?

Yeah the NHC forecast has it doing that as well, Friday to Monday going in land slowly, doubling back around the same area, able to partially feed off the Gulf for some of the time and remaining around the Texas coast for another couple of days after that, moving North East.
It's a long time to be raining on parts of Texas. Anyone know of a Hurricane Precedent?

4 PM CDT discussion. Staying near the coast is going to delay the decline of this system, leading to serious rainfall totals.

Hurricane Harvey Discussion Number
22 NWS National Hurricane Center Miami FL
AL092017 400 PM CDT Fri Aug 25 2017

Despite its concentric eyewall structure, Harvey's winds have increased during the day. NOAA and Air Force Reserve Hurricane Hunter planes have measured maximum flight-level winds of 129 kt and SFMR winds to 102 kt. Based on these data, Harvey's maximum surface winds are estimated to be 110 kt. Harvey's central pressure has also continued to fall, and the latest estimate based on dropsonde data is 941 mb. Harvey still has not slowed down, and the initial estimate is 325/9 kt.

Based on the forecast track, Harvey is expected to make landfall along the middle Texas coast tonight. After that, the track models insist that the hurricane will slow down considerably during the next 24 hours, and it is likely to move very little between 36 and 120 hours. In fact, there has been a somewhat notable change in the guidance, with very few of the models showing Harvey lifting out toward the northeast by the end of the 5-day forecast period. As a result, the NHC track forecast has been pulled back a bit and keeps Harvey near or just inland of the Texas coast through the middle of next week.

This slow motion only exacerbates the heavy rainfall and flooding threat across southern and southeastern Texas. Harvey may continue to strengthen during the 6-12 hours it has before landfall, but regardless it is expected to make landfall at major hurricane strength. Gradual weakening is anticipated after the center moves inland, but Harvey's slow motion will keep a significant portion of its circulation over water, which may slow the weakening rate. As a result, the NHC intensity forecast leans closer to the global model guidance instead of the statistical- dynamical guidance, which seems to weaken Harvey too fast. Harvey could maintain tropical storm strength for the entire 5-day forecast period due to its proximity to the northwestern Gulf of Mexico.

Key Messages: 1. Harvey will make landfall tonight, bringing life-threatening storm surge, rainfall, and wind hazards to portions of the Texas coast. Tropical-storm-force winds have moved onshore in portions of the warning areas and conditions will continue to deteriorate as the eye of Harvey approaches the middle Texas coast tonight.
2. A Storm Surge Warning is in effect for much of the Texas coast. Life-threatening storm surge flooding could reach heights of 6 to 12 feet above ground level at the coast between the north entrance of the Padre Island National Seashore and Sargent. For a depiction of areas at risk, see the Storm Surge Watch/Warning Graphic at hurricanes.gov. Due to the slow motion of Harvey and a prolonged period of onshore flow, water levels will remain elevated for several days.
3. Catastrophic and life-threatening flooding is expected across the middle and upper Texas coast from heavy rainfall of 15 to 30 inches, with isolated amounts as high as 40 inches, through Wednesday. Please refer to products from your local National Weather Service office and the NOAA Weather Prediction Center for more information on the flooding hazard.

Latest TCHP shows just about 90 kJ/cm2 in the area where Harvey intensified. This value is seen as the threshold for rapid intensification. With some cold upwelling likely the longer Harvey hangs around this may actually limit its potential over the following days.

star gazer · 25-08-2017 10:42pm

By not moving far from where it makes landfall and with all the flooding and damage, it could be a long time before it's possible to get help to many people affected. It was very fast to strengthen in the last 36 hours.
With a little time left over water, there's still a chance it becomes a Category 4 Hurricane. 95km from Corpus Christi, still moving at 17km/h.

BillyBobBS · 25-08-2017 10:48pm

Wow just seen a report there on NBC and the weather reporter basically said anyone who hasn't evacuated better make preparations for their own funeral. Talk about pulling no punches!!

I do wonder if it may have been better to have (had) mandatory evacuations on a vast scale in the 500mm-plus rainfall area given how flooding could cut much of the area off and the rising waters' threat to peoples safety. The expected area of heavy rain is so large. Of course it's tough to forecast exactly where Hurricane Harvey will go and where the worst flooding will be and what that does to normal river drainage and other channels. And forcing a lot of people out is a huge ask socially, particularly with the late notification.

Tropical Storm Alison lingered for a number of days.

It should be in the coming few hours but it is also slowing down moving NW. Moving slower now means longer/more storm surge, potential to pick up more moisture at sea and dump more rain on land.

People stay for various different reasons, such as fear of looting of property, complacency etc, since hurricanes are common there. I've been in dangerous situations before, whereby most had been evacuated, I was there out of pure curiosity and passion, I was with highly trained and experienced people, so felt safe. To be honest, I'd like to be there now, but in a safe place, which is probably difficult to find in certain areas. One of the first sites I checked last night was cameraman Geoff mackleys, he's not there, but has chased many similar storms in the past. I on the other hand do hope all that are still there are safe and well, as these systems are extremely dangerous. Putting yourself in dangerous situations is fine from time to time, provided you take precautions, in fact I'd encourage it, it's good for your well being. The power of nature should be embraced from time to time, it's an exhilarating and exciting experience, but be careful, it is more powerful than us, and we don't have all the facts all the time, I.e. it can bite back, so be prepared. I wish all caught up in this the very best

It's movement is slowing down now to 4km/h (advisory 25) Northwards, about 35km West of Victoria which must have gotten a lot of rain and wind. Harvey is also putting a lot of rain bands into the Houston area with forecasts still expecting the Houston area down to Corpus Christi to get massive rainfall accumulations.
The windspeed is slowing, down to Category 1 Hurricane, 120km/h and 984mb.
The rainfall so far:

Even on Wednesday it's now not forecast to have moved much out of the area though the winds should have weakened a lot by then, the real problem though will be the continuous rains that will come from a lingering, then former Hurricane Harvey.

Gaoth Laidir · 26-08-2017 4:30pm

I looked at that link at around 6am and the river was around 6.77 i think. Just over 3hrs later it has broken its banks at over 24 :eek: It won't take long for the motorway on the right hand side to also go under.

Now moving at just 2km/h ssw with wind strength down to 75km/h advisory 28
It should lose tropical storm status in the next day or so but the problem is the ongoing flooding and instead of looking down river at incoming hurricane force winds and storm surge, it'll be about looking upstream at how much water is coming and where the extra rain goes. It's forecast to move closer to the Gulf of Mexico again which should push up the moisture involved.

It's been like a water conveyor belt from the Gulf onto the area around Galveston - Houston and beyond. One of the things being recommended is to go to the roof of your house rather than the attic if flood waters threaten, in case of getting trapped as happened people in Hurricane Katrina. You've got to feel for the people caught up in this; the devastation of flood waters getting into homes, the danger of the floods and their relentlessness with extra rain falling all the time, rivers expecting record flooding in many if not most of the most affected areas. It's a tough time for emergency personnel but they are saving lives, it makes you appreciate the people who choose those careers as one day it might be your hand out. Stay safe Texas.

The forecast has changed again with Harvey now expected to remain a tropical storm (65km/h max sustained wind) for days and for its centre to move over water for roughly 48 hours and then go North on a path not too far West from Houston which is a worry for the rainfall.
Now forecasting isolated parts to get 1250mm total accumulations of rain, a few places have already had half that. This is an historic event unfolding with the worst coming as the flood waters rise.

Has that stream for the camera on the river gone down for anyone else?

Very frightening, I've seen someone post pictures on Facebook of an 8ft sign almost submerged on their Street. Discussions on that post are between some neighbours who've stayed in their home about going into the attic and bringing an axe in case they need to get out.
