The heavy rain from a thunderstorm that moved across the area on Wednesday afternoon has prompted a flash flood warning to be issued.
The National Weather Service said at 1:30 p.m. on Wednesday that flash flooding was possible in poor drainage areas.
“Doppler radar indicates rainfall rates with these storms of over an inch and a half an hour,” the weather service said in issuing its warning. “Flash flooding of poor drainage area is expected to begin shortly.”
The flood warning is for all of Essex County, including Hamilton and Wenham, plus a portion of northeastern Middlesex County. The warning runs through 5:30 p.m. on Wednesday.
The weather service said the warning was issued because “ flooding is imminent or occurring,” adding that anyone living near a stream and creek “should take immediate precautions.”
