Marine Zone Forecast


Synopsis: Shower and thunderstorm activity will be the primary concern into middle of this week. Some of the showers and storms may bring locally gusty conditions and possibly even a few waterspouts. A cold front approaching the waters mid week and stalling out over the region late this week into this weekend could lead to increasing shower and thunderstorm chances. There is some uncertainty with the front's progress which could impact the marine forecast later this week.
