The odds of significant cold, coastal, and marine impacts across South Florida this weekend continues to increase. An Extreme Cold Watch is in effect for the Lake Okeechobee region and coastal Palm beach County and a Freeze Watch is in effect for inland Collier, Miami Dade and Broward counties. Wind chills could drop into the 20s across all of South Florida early Sunday morning. Very breezy conditions are expected on Saturday afternoon through early Sunday morning as the strong cold front pushes through the area. Sustained winds 15-25 mph could gust up to 40 mph, with highest winds likely along the immediate coastlines. A Gale Watch is in effect for local waters beginning on Saturday afternoon and evening. Sustained winds of 30-40 knots with higher gusts is possible across the Atlantic and Gulf waters through Sunday afternoon. Wave heights could peak as high as 12 feet across the Gulf and Atlantic waters during the day on Sunday as well.
