Issued at 1040 AM EDT Tue Mar 11 2025 A pleasant morning is occurring for the Florida Keys! GOES-16 Satellite reveals that the clouds that were shading the Lower Keys this morning have retreated to the Straits and are starting to break apart leaving behind mostly sunny conditions. Temperatures along the island chain are near 70 with dew points in the mid 50s. This is a nice break in muggy air as 24 hours ago the dewpoints were in the 70s! The 12z KKEY sounding sampled very dry air above 850 mb and given this lack of moisture in our atmosphere today, mostly sunny skies will continue and very limited, if any, shower activity is expected through this evening. The fresh to strong winds that accompanied the cold front passage from yesterday evening are starting to gradually slacken this morning, now with conditions falling just below Small Craft Advisory level. Small Crafts have been taken down, but winds are still elevated, and are expected to drop more this afternoon. Small Craft Should Exercise Caution until winds decrease. Beyond dropping the Small Craft headline, no other changes were necessary to this update package. && .MARINE...
