Showers and thunderstorms kept our radar busy today, but the Big Pine Key area in particular really stood out with approximately 2.5 to 3.0 inches of rainfall in under three hours! This was enough to put low-lying areas, potholes, and parking lots temporarily under water. Confidence is high that this wetter pattern will continue through the weekend, and into the start of next week. Confidence is low regarding precise locations of heavier showers---virtually any shower will be capable of producing localized flooding, so remember TURN AROUND, DON'T DROWN if you come across flooded areas!

TODAY...Partly cloudy with a chance of showers and thunderstorms. Highs in the upper 80s. East winds near 5 mph, or near 4 knots. Chance of rain 50 percent.

TODAY...Light easterly breezes, becoming light to gentle east to southeasterly breezes. Seas across the Bay and Gulfside waters, including the southeastern Gulf waters, one foot or less. Seas across Hawk Channel and the Florida Straits around one foot. Bay and nearshore waters smooth, becoming smooth to a light chop. A chance of showers and thunderstorms.
