KEY MESSAGES

- Gentle to moderate broadly easterly breezes will prevail, peaking overnight and lulling during the day. - Rain and thunder chances peak today and tonight, and near to below normal shower and thunder chances will prevail starting tomorrow.

AVIATION

(18Z TAFS) Issued at 140 PM EDT Sun Aug 9 2026

Opting to maintain a broad VCSH for both island terminals as disorganized showers will continue to pop up and fall apart quickly over the beginning of the TAF period. Occasional MVFR CIGs are possible if showers pass over, or in the vicinity of, either air field, but any reduced categories will be very short lived as this activity is moving at approximately 15 to 20 knots. Crosswind concerns will remain very low as surface winds will continue out of the east to east southeast, but erratic winds from collapsing thunderstorms could lead to occasional crosswinds near 20 knots. Drier conditions should move in by the overnight hours.

PREV DISCUSSION

Issued at 1247 AM EDT Sun Aug 9 2026

Through this week, a deep layered ridge will remain draped across Florida as it shifts southward into Central Florida. This will help to maintain below normal moisture and weak low level inhibition. This along with the background anticyclonic flow will keep rain chances slim to none. Easterly breezes will oscillate between gentle and moderate, performing the usual lulling during the day and peaking overnight. A slight decreasing trend in winds speeds will occur through the first half of the week as the ridge nudges southward. No trend in temperatures are expected and highs will remain near 90 and lows in the lower to mid 80s. Dew points will continue in the mid to upper 70s.

MARINE

Issued at 140 PM EDT Sun Aug 9 2026

There are no watches, warnings, or advisories in effect for the Florida Keys local waters, but Small Craft Should Exercise Caution headlines may be needed for portions of our marine zones later tonight. A mix of mostly showers with some isolated thunderstorms will continue to traverse the area, leading to localized instanced of stronger winds and higher seas. Otherwise, moderate east to southeast breezes with on and off showers will continue today and tonight. Relatively drier air will gradually filter in over this week.

OF NOTE

On this day in Keys Weather History, in 1950, from the Key West Citizen, "thousands of fish were found in the streets of Key West after a heavy rain. Most of the fish were found along Caroline street between William and Grinnell. One theory was that a large waterspout had carried the fish ashore. This theory was supported by the fact that most of the fish were mullet, which swim on the surface and could be picked up by a waterspout. Caroline street regulars insisted it had rained fish, and one man said he saw a full-grown sponge fall from the sky."
