Storm Coordination Message #2 – Flash Flood and Strong Wind Potential Thursday 10/11/18-Friday 10/12/18

Hello to all…

..Tropical Storm Michael will become post tropical and intensify as a post tropical system passing well south and east of Southern New England but his interaction with a cold front and the unusually humid air mass for this time of year will set the stage for heavy rainfall with the potential of flash flooding in localized locations in Southern New England as well as strong wind gusts possibly to 40 to 50 MPH over Southeast Coastal New England..
..A Flash Flood Watch remains in effect from Thursday Morning to Thursday Night for Northern Connecticut, Western, Central and Northeastern Massachusetts for 1 to 2″ of rainfall in a short period of time and localized higher amounts possible. A Flash Flood Watch remains in effect from Thursday Afternoon to Friday Morning for Rhode Island and Southeast Massachusetts including Cape Cod for 2-3″ of rain with isolated higher amounts of 3-5″ of rain. A Flash Flood Watch remains in effect from Thursday Afternoon to Friday Afternoon for Cape Cod and the Islands for 3-5″ amounts with localized higher amounts of 4-6″. This rainfall could produce urban and poor drainage flooding and some small river and stream flooding..
..SKYWARN Activation in some form is likely Thursday into Friday with Ops at NWS Boston/Norton possible. Please note that the KA1RCI Repeater system used for SKYWARN is having link trouble and any SKYWARN Activation needed for Rhode Island will fall back to the 146.76-Scituate, RI Repeater..

A cold front will be swinging through the region today into Friday. As the cold front swings through, Tropical Storm Michael will exit off the Mid-Atlantic and intensify as a post tropical system as it tracks southeast of Nantucket. The cold front will entrain moisture from Michael and bring the potential for localized heavy rainfall and flooding to flash flooding of urban and poor drainage areas. The headlines cover the flood potential. There is also the potential for wind gusts of 40-50 MPH in two rounds one during Thursday late afternoon and evening and the other in Friday Morning into early afternoon across Southeast Coastal New England.

SKYWARN Activation in some form is likely Thursday into Friday with Ops at NWS Boston/Norton possible. Please note that the KA1RCI Repeater system used for SKYWARN is having link trouble and any SKYWARN Activation needed for Rhode Island will fall back to the 146.76-Scituate, RI Repeater. As we move into operations mode, a shortened coordination message may be posted to update the situation if time allows and ops at NWS Boston/Norton is initiated. Below is the NWS Boston/Norton Flash Flood Watch statement, Hazardous Weather Outlook and Enhanced Hazardous Weather Outlook:
