JACKSONVILLE, Fla. – Brrrr... Sunrise Tuesday (6:42 a.m.) will be COLD with lows in the upper 30s to low 40s in Southeastern Georgia and low to mid 40s in Northeastern Florida. The beaches will be in the upper 40s and low 50s. Election day will start off cold and turn sunny and cool for the afternoon. Expect to warm up to around 72° with a cool breeze out of the north between 7-12 mph. There are no chances for showers.
Wednesday also starts off chilly with sunrise low temperatures in the upper 40s to low 50s and warms into the mild mid 70s under mostly sunny skies. Winds will be out of the northeast between 7-12 mph.
Weak to building nor’easter develops on Thursday and could last for more than 10 days depending on the final outcome of Eta a super powerful Major Hurricane that will make landfall along the coast of Nicaragua later Tuesday. Winds are 150 mph gusting to 175 mph. Wow!
How does this establish a nor’easter for Jacksonville? High pressure will be keeping Eta well down south in Central America and will not relax for at least the next 10 days. Allowing Eta to move ashore, then back over the super warm waters of the Caribbean Sea, where Eta will once again re-intensify. Bad news for Cuba and possibly South Florida.
In the meantime, that strong high pressure will allow for a steady moderate onshore wind that with time will become moister and moister and that means increasing chances of coastal rains, coastal wind gusts to 30 mph, possible coastal flooding at high tides and possible beach erosion, very high rip current risks and heavy surf issues the entire 10 days stretch starting on Thursday.
Whew! No imminent serious threats but we must watch to whatever plays out in the Southern Caribbean Sea closely the next 14-16 days.
