The Nor-easter that's been churning off the New England coast the past few days has developed into Subtropical Melissa this afternoon. It's not expected to last long.

The NHC have strangely classified the ragged low pressure system in the Gulf of Mexico a tropical storm (Nestor). At most it should be subtropical as it has never had any tropical structure and is primarily being fed by an upper trough. It's only just managed to develop a circulation centre.
It's just making landfall along the Florida panhandle this morning. Water vapour ![]() 89 GHZ ![]() |

It's more like a typical MCS, but it has been producing a lot of lightning.

Here we go again?
2. Shower activity has increased this morning near the center of a large non-tropical low centered a few hundred miles southwest of the western Azores. Some additional development of this system is possible during the next couple of days as it moves generally east-northeastward. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...low...20 percent. ![]() ![]() |

That system has developed into Tropical Storm Pablo, after the other system in the western Gulf became Tropical Depression Olga a bit earlier. Both are tightly linked with extra-tropical systems and neither will amount to much.

Pablo should affect the main Azores eastern islands tomorrow afternoon and then become extratropical and fizzle out between there and here on Monday.
It's a really tiny storm, less than 100 miles across, and is under an area of very strong upper southwesterlies. ![]() |

In the Indian Ocean, Cyclone Kyarr will get up to CAT 3 over the next couple of days before dissipating harmlessly several hundred km from any land. Those lat/long grids are 2 degrees latitude (120 NM/220 km) tall.

Pablo is not really a true tropical storm but more like a medicane, only forming due to high CAPE from a cold upper trough that came down from eastern Canada during the week. SST are only around 23 C, way too low to sustaing a typical tropical system, but the cold upper air is enough to offset this and keep instability high enough to feed convection, aided by high windshear. Pablo is tiny and fairly shallow, with no real signature on microwave imagery. Its formation and is owed to totally non-tropical forces.
Ophelia had some similarities too in that it was also aided by a cold upper trough, boosting instability and also poleward outflow. But it developed more like a true tropical system and grew to be much larger and deeper. Pablo sounding from today, showing the steep lapse rates and high windshear. ![]() 85 GHz Color ![]() |

In the Indian Ocean, Kyarr has intensified further to CAT 4, and could briefly reach CAT 5 later today. The models are completely split on its track. Some say in a couple of days it will take a sharp turn to the northeast, others (and the official JTWC track) say it will turn southwest towards south of Oman. It's an interesting one to watch.
It has a lovely structure after what looks like an eyewall replacement cycle. ![]() ![]() ![]() ![]() |

That's two hurricanes now having taken an easterly route towards Ireland in the same year, even if only technically so. ![]() Quote:
