825 FXUS62 KMFL 190457 AFDMFL Area Forecast Discussion National Weather Service Miami FL 1257 AM EDT Tue Aug 19 2025 ...New SHORT TERM, LONG TERM, AVIATION, MARINE, BEACHES... .SHORT TERM... (Today through Wednesday) Issued at 1252 AM EDT Tue Aug 19 2025 Hurricane Erin remains the dominant synoptic feature through the short term period as the system makes its closest pass to South Florida today. With Erin being so far removed from South Florida, sea breezes will continue to dominate convective initiation across the area. While a few showers and storms may impact immediate coastal areas during the morning, the risk for showers and storms increases with the inland progression of the sea breezes during the afternoon hours. With northerly flow remaining well established, storms will propagate southward through the day, maximizing coverage over the southern and southwest half of the area by the evening hours. Hurricane Erin continues its northward progression on Wednesday which will veer surface flow across the area to the northwest during the morning hours and should become nearly straight westerly by the mid afternoon on Wednesday. Sea breeze showers and storms will once again during the afternoon, except with westerly flow developing, the Gulf breeze has a chance to dominate for once, and could lead to a few storms impacting east coast metro areas. Highs will range from the low to mid 90s each day with apparent temperatures in the low 100s. && .LONG TERM... (Wednesday night through Monday) Issued at 1252 AM EDT Tue Aug 19 2025 Westerly flow continues on Thursday and will potentially linger into early next week, although as we slowly lose the impact from Hurricane Erin, background flow will become weaker and weaker each day through the weekend. Each day will begin similarly, with mostly sunny conditions prevailing through the morning hours and early afternoon until the sea breezes begin to push inland. In the absence of a significant synoptic driver, the breezes and outflow boundaries continue to run the show each afternoon through the period. Initial development of storms may be close to the east coast metro areas, although coverage should be maximized across interior areas each afternoon. High temperatures will range from the low to mid 90s each afternoon with head indices in the lower 100s. Overnight lows will struggle to dip below 80 across metro areas and will range from the upper 70s to low 80s. Lows should reach the mid to low 70s for interior areas. && .AVIATION... (06Z TAFS) Issued at 1252 AM EDT Tue Aug 19 2025 VFR expected to prevail for the TAF period. Light winds continue overnight before increasing out of the north early this morning and then shifting NE in the afternoon. VCSH and VCTS today with risk for on site storms resulting in some reduced CIGs/VIS at times. APF will see the same with only difference being a northwesterly wind in the afternoon. && .MARINE... Issued at 1252 AM EDT Tue Aug 19 2025 Hurricane Erin`s outer circulation will maintain north-northeasterly winds across Atlantic waters and northwesterly across Gulf waters. Winds will veer to a more north-northwesterly direction by late Tuesday and westerly by Wednesday afternoon. Wave heights remain at one foot or less for Gulf waters today. Wave heights increase to 3-4 feet across northern Atlantic waters this afternoon. The only exception is around thunderstorms, which could provide brief periods of higher wave heights and gusty winds. With the passage of Erin to the east of the Florida peninsula mid- late week, local Atlantic waters could see an increasing north- northeasterly swell during this time period. && .BEACHES... Issued at 1252 AM EDT Tue Aug 19 2025 Increasing swell from Erin is expected as early as today, but more likely mid to late week. This will result in an increasing rip current threat for the Atlantic beaches and possible high surf concerns for Palm Beach county. There is a high risk for rip currents across Palm beach County beaches and a moderate risk for Broward county beaches. && .PRELIMINARY POINT TEMPS/POPS...
