An intense deluge of rain is expected to spark flash flooding across the region, as local meteorologists warn motorists to not drive through flooded roads and underpasses.
The summer of rain and tropical humidity unfortunately continues for Massachusetts, with several inches of rain predicted for parts of the Bay State. More than 5 inches of rain will even be possible in the next day, especially where thunderstorms develop and move over the same areas.
The National Weather Service has issued a “Flash Flood Watch” for central and western Massachusetts until Tuesday morning. Several rounds of showers and thunderstorms could drop 2 to 4 inches of rain.
“There could be some significant flash flooding from the system,” Bill Leatham, meteorologist at the National Weather Service’s Boston office, told the Herald on Sunday.
Thunderstorms will have the potential to produce rainfall rates of 1 to 2 inches per hour, which will elevate the risk of urban and street flooding along with localized flash flooding. Rivers, creeks and streams may rise out of their banks.
After the heaviest rainfall from Sunday night into Monday, some rain may linger into Tuesday before things dry out. Wednesday looks like a dry day, but it should be hot and humid.
But the dry weather pattern will be brief, with rain chances increasing through the end of the workweek.
“It will still feel quite muggy,” Leatham said.
Through Tuesday morning, New Hampshire could also see heavy downpours that may lead to flash flooding.
The state Department of Safety’s Division of Homeland Security and Emergency Management (HSEM) urges residents and visitors to be prepared before flooding occurs.
“Residents and visitors need to pay attention to local weather forecasts,” said HSEM Director Robert Buxton. “If flooding occurs, know what to do to keep you and your family safe. If you are visiting an unfamiliar area, make sure you know where there is high ground. Most flood deaths happen in vehicles. Never drive through flooded roadways.”
Meanwhile, Gov. Maura Healey has declared the week ahead as “Hurricane Preparedness Week,” recognizing the importance of preparing for the impact of extreme weather.
“As climate change fuels extreme weather across the country, every Massachusetts community must plan and prepare for the potential impact of tropical storms and hurricanes,” Healey said in a statement. “During Hurricane Preparedness Week, I encourage residents of coastal and inland areas alike to visit MEMA’s website for preparedness information, make a plan, and stay informed about how to take care of yourself and your loved ones before, during and after a storm.”
