KEY MESSAGES

Updated at 642 PM EDT Sat Sep 26 2026

- A few isolated showers across Southeast Florida this afternoon, but mostly dry weather is expected. - Hazardous marine and beach conditions continue today and will linger into Sunday. - Minor to moderate coastal flooding is expected along portions of the Atlantic coast this weekend during high tide cycles.

SHORT TERM

(Rest of today through Sunday) Issued at 247 PM EDT Sat Sep 26 2026

Thanks to dry, continental air advecting down the peninsula over South Florida, clearer skies and drier conditions are forecast throughout the weekend. As a low pressure system churns offshore of the New England coast, surface high pressure will work its way over the SE, keeping our weather pattern more quiet than usual into Monday. While low rain chances (<20%) and dewpoints ranging from high 60s to low 70s will keep our daytime weather pleasant, afternoon seabreezes could influence a few weak, boundary driven storms/showers, particularly over the coastal eastern metros. Throughout Sunday, winds will relax with the surface pressure gradient weakening, returning South Florida to a more seabreeze dominated wind regime. Despite the wind shift, the chance of an isolated storm/shower forming along the seabreeze remains low (<15%). Hazardous beach/marine conditions are forecast into the weekend as a result of increased wave heights courtesy of the NE low pressure system. Dangerous swimming and surf conditions are expected across the east Atlantic coast, along with a risk for minor to moderate saltwater coastal flooding. Take caution when heading to the beach this weekend, if in doubt, don't go out!

High temperatures are to remain primarily in the upper 80s this weekend, with areas near the lake potentially peaking in the mid 80s. Overnight lows Saturday/Sunday night range from the low to mid 60s near the lake to the upper 60s and low 70s elsewhere.

LONG TERM

(Sunday night through Friday) Issued at 234 AM EDT Sat Sep 26 2026

For early next week, the potent low pressure in the northeast US will shift more northwards as a mid-to-upper level shortwave trough pushes across the central US and deepens across the Mid- Atlantic and Southeast US regions. As this trough swings through the Florida Peninsula in the Monday to Tuesday time frame, low level flow will shift back to a southerly to southwesterly direction and result in the return of deeper tropical moisture advection. With this increasing moisture returning and the shortwave trough providing some upper level forcing for ascent, rain chances will increase back to the 60-80% range by Tuesday and into the middle of next week across South Florida. Steady moisture advection is then expected to continue through the end of the week.

For the end of the week, ensembles are hinting that the subtropical high in the western Atlantic will re-build and expand further east, resulting in a return to steady easterly flow. This setup favors the highest rain chances over SW Florida (65-80%) with slightly lower chances across SE Florida (50-60%) by Friday and into next weekend. Essentially, this pattern suggests the most widespread activity will be seen over SW Florida with more scattered activity over the east coast metro areas.

High temperatures will rebound slightly through the period, with highs each day reaching anywhere from the upper 80s to low 90s. Overnight lows will be a few degrees cooler through Monday night with the front clearing the area, with lows near the lake region in the low to mid 60s and the rest of the region seeing lows in the upper 60s to low 70s. By Tuesday night and beyond, overnight lows will increase back into the mid to upper 70s.

AVIATION

(00Z TAFS) Issued at 642 PM EDT Sat Sep 26 2026

VFR conditions will persist through the rest of the evening and night at all sites. Light and variable winds after sunset. Winds will start to pick up slightly during the afternoon hours on Sunday as diurnal sea breezes start to push inland.

MARINE

Issued at 234 AM EDT Sat Sep 26 2026

Hazardous conditions are expected to linger across the Atlantic waters this weekend. Moderate northerly winds today will weaken more on Sunday, but a northerly/northeasterly swell continues due to a strong system in the northeast. Thus, seas are still expected to reach 6-8 feet through Sunday morning. With these wave conditions, Small Craft Advisories remain in effect through Sunday morning but are expected to drop off after that as calmer conditions return heading into next week.

BEACHES

Issued at 234 AM EDT Sat Sep 26 2026

A high risk for rip currents continues for all Atlantic coast beaches as an increasing northerly/northeasterly swell and brisk northerly winds continue. In addition, the High Surf Advisory remains in effect for the Palm Beaches for big breaking waves of up to 7-8 feet today.

Furthermore, the King Tide Cycle this weekend is expected to result in more periods of coastal flooding. Observations continue to out- perform guidance by a decent margin and thus we could see minor to moderate flooding. Based on today's observations, there is a good chance that Palm Beach and Broward coastlines reach moderate flooding, while Miami-Dade should remain at minor. The Coastal Flood Statement has been upgraded to a Coastal Flood Advisory for Palm Beach and Broward, with the Coastal Flood Statement remaining in place for Miami-Dade. Both of these products will run through Sunday morning.
