.SYNOPSIS...

Atlantic high pressure centered near Bermuda will continue to
extend its axis across our local waters through the weekend. This

afternoon sea breezes over the near shore waters bringing speeds
up to Caution levels, while a southerly wind surge results in
Caution conditions offshore this evening. Late afternoon and
evening thunderstorms are likely across our local waters through
Saturday, with coverage then expected to decrease slightly from
Sunday through the middle portions of next week.
