KEY MESSAGES

- A Coastal Flood Statement remains in effect. Low lying areas will see minor saltwater ponding around the times of high tide.

- A weak front remains just north of the Island Chain early this morning. This will lead to low to medium chances for showers and thunderstorms over the next few days.

FORECAST

A weak front will remain draped nearby the area today. The front has not yet moved through the Island Chain and there remains the possibility that it does not press through remaining just north across the SE Gulf waters. This will keep moisture across the region for today resulting in slight chances. Slight chances continue for tonight as well. Mean layer ridging across the northwest Gulf along with the weak frontal boundary will continue to promote gentle to moderate northeast to east breezes, at times moderate breezes.

MARINE

Issued at 505 AM EDT Tue Oct 13 2026 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, high pressure remains across the Southeast U.S. and the northern Gulf. An Atlantic ridge continues to weaken and retreat east towards the central Atlantic. In between these two features lies a weak cold front which has stalled across the northern SE Gulf waters of the Keys early this morning. Latest indications are for this front not to pass through the Keys but rather remain just north. This will promote gentle to moderate northeast to east breezes over the next several days. There will be slight chances to chances for showers and a few thunderstorms over the next few days as this weak and diffuse front remains nearby the area. Late in the week, a strong cold front could develop and move towards the Florida Keys. Currently, there are low chances that the front will make it to the Florida Keys waters. We will continue monitoring this system.

AVIATION

(06Z TAFS) Issued at 505 AM EDT Tue Oct 13 2026 A weak front looks like it has stalled just north of the region across the northern Gulf waters of the Keys. While VFR conditions are largely expected through the TAF period, there remains the risk for showers and thunderstorms nearby either terminal through the TAF period. However, due to timing and placement uncertainty, VCSH was not included in the TAF at this time. Near surface winds will remain northeasterly through the period.
