The weather crew have been tracking a rapidly intensifying low that is expected to track northeast across Ireland Tuesday night. By late afternoon this will be near or just southwest of Valentia at 947 mb, and winds from the southeast to south could gust over 120 km/hr near the south coast and in exposed locations inland. In early stages of the storm, heavy rain and southeast to east gales will spread over most regions (30 mm rains could bring rapid onset of flooding; strong winds and high tides could combine to produce another round of coastal flooding).
By later Tuesday evening, with the centre near Shannon, very strong winds will rapidly spread north up the east coast affecting Wicklow and Dublin.
Although some areas will see slack winds for a time Tuesday night, a later phase of the storm will involve moderate to strong westerly winds in most regions.
Although I have started this discussion with a level 2 title, it would not be out of place to mention level 3 concern for coastal flooding and even some isolated wind gusts over 130 km/hr. I am fairly confident that the offshore Kinsale energy platform will record gusts near 90-100 knots and some of the more exposed south coast stations could see 70-80 knots, if brief in duration, due to the forward speed and strong gradient of this storm.
I wanted to start a new thread partly to have editing capability during the late overnight when it may be more possible to assess the exact details of this dangerous storm.
We are of course also concerned about potential for Saturday's deep low.
