Issued at 315 AM EDT Sun Mar 29 2026

- A Wind Advisory remains in effect along the coast east of I-95 for winds of 20 to 30 mph and gusts to 40 mph.

- Hazardous to dangerous beach and boating conditions persist as a result of the strong winds and high seas. Entering the ocean as either a swimmer or a mariner is strongly discouraged!

- Scattered shower and isolated storms will remain possible across east central Florida today and Monday, becoming more isolated and diurnally-driven from Tuesday onward.

DISCUSSION

Issued at 315 AM EDT Sun Mar 29 2026

Today-Tonight...An area of high pressure situated across the Mid- Atlantic will shift offshore across the Atlantic Ocean through today. This high will help push the cold front that moved through the area further south, with the boundary anticipated to stall across south Florida. Across east central Florida, a tight pressure gradient will remain in place as a result of being wedged between these two features, causing easterly winds to remain breezy to windy and gusty areawide today. A Wind Advisory remains in effect along the coast east of I-95 through 4 PM for winds of 20 to 30 mph and occasional gusts to 40 mph. These strong onshore winds will also continue to support building seas across the local Atlantic waters, leading to persistent poor to hazardous conditions at all east central Florida beaches. Rough surf and a high risk of rip currents are anticipated along with breaking waves of 6 to 11 feet. A High Surf Advisory remains in effect. Entering the surf is not advised.

Between the lingering plume of moisture along the frontal boundary and the strong onshore flow, moisture will be plentiful across east central Florida today. Isolated to scattered onshore- moving showers are forecast areawide, but the highest rain chances are focused across the Treasure Coast counties and near Lake Okeechobee, which is where PWATs are forecast to be highest (1.4-1.6"). While instability generally looks poor across east central Florida today, any daytime heating may provide just enough energy for some isolated storm development in combination with the onshore flow. Primary storm threats with any activity that does manage to develop would be lightning strikes and wind gusts to 40 mph. Confidence in storm development remains low. Shower and storm activity is anticipated to continue into the overnight hours, with the best rain chances focused along the immediate coast tonight.

In the wake of the cold front passage, cooler air has filtered in from the north. Near to slightly below normal afternoon highs are forecast across east central Florida, with temperatures reaching the low to mid 70s. Overnight lows remain relatively unchanged, falling into the low to mid 60s areawide.

Monday-Tuesday...The stalled boundary gradually washes out through early week, with the high pressure situated across the western Atlantic remaining generally just north of the local waters. The ridge axis will gradually drift southward towards Georgia, causing winds to become more southeasterly Monday and Tuesday. The pressure gradient is anticipated to slacken, with winds finally subsiding across east central Florida. Local enhancement each afternoon caused by the east coast sea breeze is forecast, with wind speeds reaching 15 mph as the sea breeze moves inland. While the winds will be weaker, it is important to note that poor to hazardous beach conditions are anticipated to persist due to lingering swells and wave heights. The High Surf Advisory will continue at the Treasure Coast beaches through 4 PM on Monday, and the high risk of rip currents is anticipated to persist over the next few days.

Persistent onshore flow will continue to advect moisture towards east central Florida through early this week, with onshore showers anticipated to continue. Rain chances of 40-60% are forecast on Monday, falling to 30-50% on Tuesday. The highest coverage of showers is forecast each afternoon across the interior portions of east central Florida, driven primarily by the combination of onshore flow and the progression inland of the sea breeze. Isolated storms cannot be ruled out on Monday so left in a low chance (20%) within the forecast. Confidence wanes into Tuesday, so have left out mention of it within the forecast for now but would not be surprised if it is eventually added in during a future forecast package. Shower and storm activity will diminish into the evening and overnight hours each day.

Temperatures begin a gradual warming trend through early week, with highs reaching the upper 70s to low 80s in the afternoons. Lows remain in the low to mid 60s during the overnight hours.

Wednesday-Saturday...High pressure is forecast to remain situated across the western Atlantic through the extended period, with the ridge axis staying just north of east central Florida. This will keep east to southeast flow locally through the rest of the week. The east coast sea breeze is anticipated to develop each afternoon and move inland, with diurnally-driven showers and isolated storms forecast each afternoon. Rain chances remain between 20-30% with the highest chances focused across the interior. Activity is anticipated to diminish each evening, with mostly dry conditions through the overnight hours. Temperatures will continue to follow the warming trend, reaching above normal values for afternoon highs by the middle of the week nearly areawide.

MARINE

Issued at 315 AM EDT Sun Mar 29 2026

The local Atlantic waters will remain wedged between a strengthening high pressure to the north and a stalled boundary to the south, resulting in persistent onshore winds and gusty conditions. Easterly winds reach 20 to 30 knots today, with occasional to frequent gale- force gusts anticipated. A Gale Warning remains in effect across the waters through early morning, transitioning to a Small Craft Advisory late this morning as winds begin to gradually subside. These strong and gusty winds will result in seas of 10 to 15 feet across the local waters. Winds subside to 15 to 20 knots by Monday, but seas will be slower to respond. Seas remain above 7 feet across portions of the local waters through at least Tuesday night, and additional extensions of the Small Craft Advisory will likely be needed. Boating conditions will remain poor through most of the extended period due to persistent onshore flow.

Plentiful moisture across the area will lead to continued isolated to scattered shower development across the local waters today through Monday, and isolated storms cannot be fully ruled out. Rain chances decrease to 10-30% from Tuesday onward.

AVIATION

(12Z TAFs) Issued at 640 AM EDT Sun Mar 29 2026

A tight pressure gradient in place with current onshore sustained wind speeds 10-20 kts and frequently gusty, 15-30 kts. Scattered, onshore-moving, convection through the day with brief downpours and gusty winds. An isolated lightning storm threat will exist, greatest chances near MLB southward. Brief IFR with convection, otherwise generally MVFR with pockets of low VFR during the day with coverage mainly BKN-OVC into tonight. Expect ENE/E winds to remain breezy/gusty with a gradual diminishing of speeds this evening and overnight over the interior, but still remaining elevated along the coast.
