That was the advice Friday as heavy rains battered the Bay State and were expected to continue overnight, prompting flood watches across Massachusetts as the Commonwealth caught the remnants of Tropical Storm Andrea.
The National Weather Service in Taunton issued flood watches, warnings, and high surf advisories from Boston to the Berkshires and said the storm would probably track northward through the state overnight somewhere between the South Shore and Nantucket.
All told, areas northwest of the Cape Cod Canal could expect 2 to 4 inches of rain, with some areas seeing upwards of 5 inches, forecasters said. Parts of the Connecticut River Valley and the Berkshires would probably see 2 to 3 inches of rain in a six-hour span.
Another concern from the rains was the North Nashua River in Fitchburg, which the Weather Service said could rise above flood stage after midnight and crest near 7.8 feet by 8 a.m. Saturday.
The Weather Service warned that if the river crests at 8 feet, “flooding of low-lying areas along the river can be expected from Fitchburg downstream into Lancaster.”
The river was expected to fall below flood stage by Saturday afternoon.
Deputy Fire Chief Dave Rousseau of Fitchburg said that authorities were monitoring the situation and that there is a sheltering plan in place in the event of flooding for people who live in the dozens of homes near the river.
“It is flowing pretty good, but as of right now it’s not cresting,” Rousseau said.
The Department of Transportation was also ready Friday to respond to weather-related issues on state roads, a spokesman said.
“We have maintenance crews in all six of our highway districts prepared to respond with personnel and equipment, should it be necessary,” spokesman Michael Verseckes said.
The Weather Service said things should start drying out by noon Saturday, with highs in the lower 70s, and Sunday should bring partly sunny skies, west winds, and highs in the upper 70s.
But the wet weather could return next week. Meteorologist Alan Dunham said showers are possible Monday through Wednesday, and temperatures should be in the mid-70s.
