KEY MESSAGES

Issued at 235 PM EDT Sat Oct 3 2026

- A wet, unsettled pattern is forecast to persist across east central Florida through this weekend and next week. Minor flooding, lightning, and gusty winds will be possible with activity.

- A high risk of rip currents continues through the remainder of today and is expected to persist through the rest of the weekend at all east central Florida beaches. Entering the surf is not advised!

- Near to slightly above normal temperatures continue through early next week across east central Florida. Peak heat indices of 100F and greater in some spots cannot be ruled out. Remain adequately hydrated!

DISCUSSION

Issued at 235 PM EDT Sat Oct 3 2026

Through Tonight...A slower start to shower and storm development today, with higher coverage of clouds this morning helping to limit daytime heating slightly. However, as clouds have cleared a bit into this afternoon and an outflow boundary from activity earlier near the Treasure Coast has pushed northward, isolated showers and storms have started to develop. Increasing coverage of activity is anticipated over the next several hours, with the best chances focused primarily across the interior (40-50%). Persistent 10 to 15 mph steering flow will help keep showers and storms moving, with less of a concern for flooding through the remainder of today. Instability from daytime heating will support isolated storm development, with occasional lightning strikes and wind gusts of 45 to 50 mph possible. General storm motion will be to the north-northwest. Hi-res guidance favors activity diminishing into the late evening and overnight hours, with mostly dry conditions anticipated across the peninsula. Isolated showers cannot be ruled out across the local Atlantic waters, but there is low confidence in this. Overnight temperatures fall into the 70s, warmest along the coast. A high risk of rip currents continues overnight at all east central Florida beaches and will likely be extended into tomorrow. Entering the surf is not advised.

Sunday-Monday...Mid-level ridging situated across the Florida peninsula slowly weakens through Sunday, with a broad trough extending southward towards Florida into Monday. At the surface, high pressure across the Atlantic gets kicked farther offshore on Sunday as a front slowly pushes across the southeastern US, where it is then anticipated to push into north Florida on Monday. A moist air mass will remain in place across the Florida peninsula thanks to both south to southeasterly flow at the surface continuing to advect moisture towards the area and the frontal boundary pushing moisture out ahead of itself towards Florida. While PoPs on Sunday are forecast to remain fairly similar to today (30-50%), there is an uptick in chances on Monday (50-70%) as the frontal boundary approaches. Rain chances will follow a fairly diurnal pattern on Sunday, with the sea breeze assisting in development as it pushes inland. Monday, the pattern is driven more by the frontal boundary, though additional support by the sea breeze will also help. Given the multiple prior days of rainfall, minor flooding is expected to be a concern through the remainder of the weekend and into early next week, especially as model guidance indicates the potential for some weaker steering flow. Isolated to scattered storm activity will also be possible each afternoon, though modest instability could be a limiting factor to more robust development. Lightning strikes and wind gusts of 45 to 50 mph will be possible with any activity that does develop. While showers and storms are forecast to slowly diminish into the overnight hours on Sunday, lingering activity across the peninsula on Monday cannot be ruled out given the front to the north. Scattered shower and even storm development across the local Atlantic waters will be possible each night.

Given the moist air mass and the predominant south to southeast flow, temperatures are anticipated to remain warm across east central Florida, staying near to slightly above normal. Highs reach the upper 80s to low 90s each afternoon, combining with the humidity to produce peak heat indices of 100F and greater nearly areawide. Hydration will be key for those spending extended periods of time outdoors. Overnight, temperatures remain near to slightly above normal in the low to mid 70s.

Tuesday-Friday...Through the remainder of the upcoming week, an unsettled pattern is anticipated to persist across east central Florida. The aforementioned broad mid-level trough situated across the southeastern US is forecast to remain in place, with some indication of shortwaves moving along it throughout the week. At the surface, the frontal boundary approaching from the north is forecast to stall across the peninsula, generally meandering across central Florida. There are some indications for the development of a low along the stationary boundary off the northeast Florida coast towards the middle of the week, which would have implications on beach and boating conditions. There is some uncertainty relative to timing of development and strength of the low. This will continue to be closely monitored and confidence in the outcome will increase as model guidance comes into better agreement on a solution. Overall, a plume of moisture along the boundary will support continued higher coverage of showers through next week, with PoPs staying elevated (60-80%). Flooding will remain the primary concern locally, especially given the multiple days of rainfall and saturated soils. Isolated to scattered storm development will be possible with activity, with lightning and gusty winds anticipated to be the primary storm- related hazards. Current guidance trends follow a somewhat diurnal pattern with afternoon and early evening forecast to be the peak coverage of showers and storms, though lingering activity across the peninsula and ongoing development across the local Atlantic waters through the nighttime hours cannot be ruled out. Outside of showers and storms, northerly flow is forecast to develop through the middle of next week, with winds gradually becoming more onshore later. Temperatures are forecast to remain generally near normal values, though the moist air mass will cause peak heat indices to continue creeping towards 100F in some spots, especially across the Treasure Coast.

MARINE

Issued at 235 PM EDT Sat Oct 3 2026

Broad high pressure across the Atlantic is shoved farther east as a frontal boundary drifts southward across the southeastern US, with the boundary becoming stationary across the Florida peninsula next week. While boating conditions are anticipated to remain generally favorable through at least Tuesday, there is indication that conditions could deteriorate and become poor to hazardous mid to late week as a low develops along the stationary boundary just north of the local waters. There remains some uncertainty relative to the strength of the low, but confidence in evolution should increase as time moves forward.

Seas are forecast to remain generally between 2 to 4 feet tonight through Tuesday, with wind speed staying below 15 knots. Southeasterly winds tonight through Sunday become more southerly into Monday, with a shift more onshore each day as the sea breeze develops. By Tuesday, winds become more variable with the potential for the developing low north of the waters. Wednesday, northerly winds of 10-15 knots support building seas of 3 to 6 feet, highest across the Gulf Stream waters. Brief periods of 7 foot seas cannot be ruled out. A wet pattern will also persist across the local Atlantic waters through this weekend and into next week, with scattered to numerous showers and isolated to scattered storms possible. Storm hazards will include lightning strikes, wind gusts in excess of 30 knots, heavy downpours, and locally higher seas.

AVIATION

(18Z TAFs) Issued at 124 PM EDT Sat Oct 3 2026

Abundant moisture will continue to provide for a few showers and storms through the TAF period, though timing is of lower confidence than desired. We expect some development near and esp west of MCO this afternoon and early evening, before conditions look quieter into much of the night. Additional redevelopment of showers is expected Sunday morning closer to the coast. SE flow persists up to 12 kt with predominant VFR outside of convection.
