Low Pressure Forming Over The Eastern Gulf Of Mexico Will Bring Another Round Of Rain To The Florida Peninsula From Wednesday Night To Friday: Satellite imagery, radar loops and surface analysis indicates that there will be two areas of low pressure that will impact the Florida Peninsula throughout the rest of this week.
The first low pressure system is currently located over the easternmost Gulf of Mexico and this weather system is currently producing some shower and thunderstorm activity from Sebring eastward to Palm Bay and Port Saint Lucie. Additional heavy shower and thunderstorm activity is pushing eastward from the eastern Gulf of Mexico and will mainly impact central and northern Florida from about the I-4 corridor and points north from this afternoon into early this evening before it pushes offshore after about 8-9 pm this evening. Rainfall amounts from today into this evening will range from less than one tenth of an inch across south Florida to one quarter to one half of an inch along and north of I-4 across central and north Florida.
A second low pressure system is expected to form over the eastern Gulf of Mexico on Thursday and will track across central Florida on Friday before it pushes offshore on Friday night and Saturday. This second low pressure system will bring the following weather hazards over the Gulf of Mexico and the Florida Peninsula from Wednesday to Friday.
Marine Hazards For The Gulf Of Mexico From Wednesday To Friday: Gale force winds are expected to impact the western and northern Gulf of Mexico starting on Wednesday with gale force winds continuing through Thursday. These gale force winds will spread into parts of the eastern Gulf of Mexico from Thursday into Friday.
Rainfall Will Impact Parts Of The Florida Peninsula From Wednesday Night To Friday: Rainfall with the second low pressure system will begin to impact northern Florida and southern Georgia on Wednesday afternoon and Wednesday evening and will spread across the rest of the Florida Peninsula during the day on Thursday and will continue through Thursday night and Friday.
Total rainfall amounts of one half to one inch will impact much of the Florida Peninsula from Wednesday night to Friday. Up to 2 inches of rainfall could impact northern Florida and southern parts of Georgia.
