..A Coastal Flood Advisory is in effect from 10 PM Saturday Evening to 2 AM Sunday Morning for East Coastal Massachusetts including Cape Cod and Nantucket Island for minor coastal flooding at the time of high tide..
..SKYWARN Activation with Ops at NWS Boston/Norton will be monitoring the situation starting at 830 AM today lasting throughout the day and evening..
A stalled out frontal boundary coupled with waves along the frontal boundary will set the stage for convective heavy showers and isolated thunderstorms. As those heavy showers and thunderstorms train over the same area, it will set the stage for the potential of flooding across those areas. Not all areas will see flooding but those areas that see persistent heavy rainfall from showers and thunderstorms training over the same area will be the locations that see flooding. There is also the low risk for an isolated strong to severe thunderstorm. The scenario is not quite as potent as last Saturday but something that will also bear watching in addition to flooding. There is also the potential for minor coastal flooding at the time of high tide late Saturday Night. The headlines detail the Flash Flood Watch and Coastal Flood Advisory in effect for the area.
SKYWARN Activation with Ops at NWS Boston/Norton will be monitoring the situation starting at 830 AM today lasting throughout the day and evening. This will be the only coordination message as we move into operations mode.
