KEY MESSAGES

Updated at 732 AM EDT Tue Oct 20 2026

- Dangerous surf conditions today for the Palm Beach and Broward beaches.

- Minor to moderate coastal flooding possible mid to late week.

SHORT TERM

(Today through Wednesday) Issued at 103 AM EDT Tue Oct 20 2026

Latest analysis shows a stalled frontal boundary along the FL Straits, surface low pressure well off the Mid Atlantic coast, and strong high pressure over eastern Canada. At the upper levels, there is ridging over the center of the country and upper level lows off both coasts of the US. Overall, the pattern won't change much today or Wednesday. Latest 00Z sounding shows a lot of mid and upper level dry air and forecast soundings show the dry air aloft remaining in place. There will be enough low level moisture in place with the steady N/NE breeze for widely scattered showers to continue across the east coast metro, with overall fairly dry conditions over the interior and SW FL.

High temperatures both today and Wednesday will be in the low to middle 80s across the east coast metro and around Lake Okeechobee, and mid to upper 80s over SW FL and the southern Everglades. Low temperatures tonight will range from the low to middle 60s across SW FL, to upper 60s and lower 70s across SE FL.

LONG TERM

(Wednesday night through Monday) Issued at 103 AM EDT Tue Oct 20 2026

As we head towards the end of the work week, heights continue to fall across the region and eventually an upper level low will form in the vicinity of Cuba over the weekend. Wrap around moisture will increase rain chances, especially across the east coast metro. In addition to the higher rain chances, the pressure gradient will tighten once again as strong high pressure builds into New England. Expect breezy NE winds this weekend into early next week, with early indications of wind gusts of 30-40 mph possible, especially along the coast.

High temperatures during the extended period will be fairly consistent, ranging from the low to middle 80s each day. Overnight temps will be in the 60s/70s.

AVIATION

(12Z TAFS) Issued at 732 AM EDT Tue Oct 20 2026

VFR conditions will prevail throughout the forecast period. NE winds will increase after 15z and range between 10 to 15 kts through the afternoon hours. Wind gusts of 20 to 25 kts will be possible across all terminals after 15z. Scattered showers will remain possible near the east coast terminals mainly through the early afternoon hours.

MARINE

Issued at 103 AM EDT Tue Oct 20 2026

Hazardous marine conditions will continue through mid week with NE winds 20-25 kts today decreasing to 15-20 kts on Wednesday. Seas in the Atlantic 8-12 ft today decreasing to 4-8 ft on Wednesday. Seas in the Gulf 3-6 ft today and 1-3 ft on Wednesday. Hazardous seas will likely linger in portions of the Atlantic waters through the end of the week, and then hazardous conditions for all local waters are expected this weekend as an upper level low forms to our south in the Caribbean and the pressure gradient locally tightens.

BEACHES

Issued at 103 AM EDT Tue Oct 20 2026

Strong NE flow and dangerous swell will result in a high risk of rip currents continuing for the Atlantic coast through at least Thursday. In addition, large breaking waves in the surf zone is expected along the Palm Beach coast through Wednesday morning and Broward coast through this evening.

With the upcoming King Tide cycle, minor to moderate coastal flooding is possible beginning mid week and lasting through at least the upcoming weekend around the high tide cycles each day.
