1037pm EDT Tuesday Oct 28 2025

Issued at 936pm EDT Tuesday Oct 28 2025

Hurricane Melissa will continue to march northeastward and move across eastern Cuba beginning late tonight. This track will keep Melissa from having any direct impacts on the Keys. However, there may be some lingering effects over the next few hours due to a confluent zone setting up across our area, between Melissa to our southeast and ridging across the Gulf. Current radar imagery indicated a spotty band of showers stretching from the vicinity of the Upper Keys to the outer southwestern Florida Straits. A number of island locations in the Middle and Upper Keys have been affected by some of this activity through the evening.

As Melissa lifts further northeast, weak high pressure will be shoved southeastward closer to the Keys by a cold front advancing across the northwestern Gulf. This lead to winds backing further north and strengthen slightly. This will both push the confluence zone out into the Straits and let surface dew points drift downwards into the lower to mid 70s. As a result, drier conditions are expected late tonight, but in the meantime, current activity justifies holding slight chance Probability of Precipitation for the overnight. Expect overnight lows to settle in the mid to upper 70s.
