A wave in the east Atlantic now has a 70% chance for development, no invest tag. As of right now, odds favor a recruve before the Caribbean islands, but it may be close. Leewards and Bermuda should keep watch during the week.

Low pressure/tight gradient north of the Cape on Labor Day
      #115822 - Mon Sep 01 2025 10:06 AM

Conditions along the Volusia coast deteriorated overnight. I measured nearly an inch of rain with this morning's 24-hr observation. Squally bands of moderate to heavy rain were accompanied by northeast wind gusts to 35 mph. Lots of palm branches down in the yard compliments of nature's most robust self-pruning effort of this summer. Not the greatest weather for visitor's Labor Day at the beach.

From MLB NWS morning discussion:

Marine conditions have deteriorated over the local Volusia coastal waters as low pressure creates a tight pressure gradient with northeast winds increasing to near 20 knots with frequent higher gusts. Seas will also build 5 to 7 feet across the Volusia waters.

The pressure gradient remains rather tight near Melbourne northward today. As such, may see periods of breezy/gusty NE winds - highest
along the coast, esp Volusia County. Not sold on a Windy Advisory (WI.Y) for Volusia/Brevard just yet, but it bears watching as wind speeds are forecast to approach 20 mph this afternoon/early evening and we could see frequent gusts to 25-30 mph along the Volusia coast. A building swell will increase the rip current risk to HIGH today for Volusia/north Brevard counties with numerous, strong, life-threatening rip currents expected, as well as for increasing ROUGH Surf.

Sunday afternoon, I noticed rain and some banding moving SW towards Orange County. By 2200, I am realizing that there is a low pressure area off the Cape.

It will be a little cooler today.

A weak low pressure center is forming off the coast of Cape Canaveral this evening based on radar observations. https://t.co/LpijcuakYM

In DBS at 1 pm observing conditions bordering on tropical storm force with a NNE wind of 25 mph gusting to 35 mph with intermittent light to moderate rain. The Atlantic looks like "Victory at Sea" with 5-6 ft breakers and a heavy north to south current. Looks like the tightest gradient winds extend from the Cape north to St Augustine:

DAYTONA BEACH PTSUNNY 80 74 81 N24G31 29.94R
ST AUGUSTINE CLOUDY 81 72 74 N22G31 29.98F

Tropical development wise this is too elongated sw-ne to get going, and likely to get stretched out more. Still it's pulling in some bands. However isolated some of it will be gusty, It's interesting for sure, I think the mesoscale models like HRRR show this best, but still not enough to get fully tropical. There's probably going to be a few more of these that the models really won't handle well off it. It's probably one of the most interesting things to watch closeby this week, even if development is unlikely.
