The NOS water level gauges at Key West Harbor and the west side of Vaca Key, in addition to the National Park Service gauges Bayside of the Upper Keys, indicate high tide water levels very near Coastal Flood Statement. The predicted tides for the next several days will increase slightly, all due to the new moon. Finally, a mid latitude low pressure system east of the Carolinas will disrupt the flow of the Gulf Stream for the next several days, which may result in an increase in water levels across the Keys. Coastal Flood Statements are in effect for all of the Florida Keys. Isolated to scattered thunderstorms will be possible. The primary hazards will be gusty winds and cloud to surface lightning strikes. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Isolated to scattered thunderstorms will be possible mainly Sunday through Thursday. The primary hazards will be gusty winds, cloud to surface lightning strikes, and locally heavy rainfall. There is a slight chance for strong to severe thunderstorms Sunday night through Wednesday due to adequate deep layer shear and instability. These storms will be capable of damaging wind gusts. A tropical low pressure system is expected to develop in the southwestern Caribbean Sea early next week. While uncertainty remains high, this system is expected to advance east northeastward through the first half of the week and push across the Florida Peninsula around mid week. As a result, a few days of locally heavy rainfall and fresh to strong southerly to westerly breezes are becoming increasingly likely. Rainfall totals for early through mid week will range between 4 and 6 inches, with locally higher amounts. The Weather Prediction Center placed South Florida and the Keys in a Marginal Risk (5-15% chance) for Excessive Rainfall on Sunday night through Tuesday. Small Craft Advisories may be required. .SPOTTER INFORMATION STATEMENT... Spotter activation is not expected at this time. $$
