Until midnight, isolated showers will work quickly west-northwest at

Keys, including Hawk channel and the Straits of Florida. These
showers will produce brief periods of reduced visibility and
localized wind gusts reaching 25 to 30 knots within pockets of
moderate rainfall. Over the last couple hours, a few of these
showers have spritzed locations in Key Largo, and we can not rule
out a few more similar episodes.
