A flash flood watch has been issued for several counties in MA ahead of afternoon storms expected to impact the region.
The watch was upgraded to a warning mid-afternoon for Franklin, Hampden, Hampshire, Middlesex, Norfolk and Suffolk counties.
"Copious amounts of monsoonal moisture will continue to stream across Southwestern California through Thursday", according to the report.
The warning isn't atypical, but the weather conditions have pushed the thunder farther inland than usual. "This will bring a risk of flash flooding, especially to interior sections".
"Drivers could be washed off the road", Andrew Rorke with the National Weather Service says. "We don't want that to happen again and we want to make sure that while we can't stop a flash flood, we can let people know", Lewin added.
Strong winds, rain and street flooding swept across Riverside and San Bernardino counties Tuesday afternoon, and The U.S. Open of Surfing in Huntington Beach sent thousands of fans home early due to fears of lightning strikes.
Flash flooding and debris flows will be a particular threat in and below the recently burned areas.
A Flash Flood Warning means that flooding is imminent or occurring. Flash flooding is a very risky situation.
