Storm Coordination Message #1 – Wednesday Night 8/28/19-Thursday Morning 8/29/19 – Flash Flood/Heavy Rainfall Potential
Hello to all…
..A cold front moving across New England late Wednesday Afternoon through Thursday Morning coupled with moisture from offshore Tropical Depression Erin will set the stage for widespread general rainfall and the potential for flash flooding of urban and poor drainage areas and possibly some small streams. A Flash Flood Watch is in effect for Central and Eastern Massachusetts and Rhode Island through late Wednesday Night for 2-4″ of rainfall with localized amounts of up to 5″ possible. Western areas should monitor but are expected to receive less rainfall..
..An isolated strong to severe thunderstorm with strong to damaging wind, frequent lightning and heavy downpours cannot be ruled out during the evening and overnight hours..
..SKYWARN Activation with Ops at NWS Boston/Norton will commence by 530 PM EDT Wednesday Evening through late tonight to monitor flash flooding and any isolated severe weather potential..
A cold front approaching from New York State will move its way through New England tonight and tap into a moisture feed from Tropical Depression Erin to bring heavy downpours and perhaps a few embedded thunderstorms to the area. The headlines depict the current thinking regarding heavy rainfall and flood potential. Key factors include:
1.) Whether any heavy training rainfall will track over a given area to result in the higher end rainfall amounts.
2.) Whether any heavy training rainfall will track over vulnerable urban areas or areas of more flashy small streams/rivers.
3.) Any thunderstorm development that enhances heavy rainfall.
SKYWARN Activation with Ops at NWS Boston/Norton will commence by 530 PM EDT Wednesday Evening through late tonight to monitor flash flooding and any isolated severe weather potential. Below is the NWS Boston/Norton Flash Flood Watch Statement, Hazardous Weather Outlook and Enhanced Hazardous Weather Outlook:
