So much for this morning’s showers. The rain is coming down hard now as remnants of Tropical Storm Andrea stream through Massachusetts — and with more than 5 inches of rain possible in some areas, forecasters are already warning of minor flooding along at least one of the state’s streams.

The remnants of Andrea have joined with an Ohio Valley low that moseyed into the region last night, the National Weather Service said.

Andrea is expected to track northward through the state somewhere between the South Shore and Nantucket overnight, meteorologist Alan Dunham said. As with any fast-moving tropical system, heavy rain will fall to the west of the storm system and heavy winds will flow toward the east, he said.


All told, areas northwest of the Cape Cod Canal can expect 2 to 4 inches of rain, with some areas seeing upwards of 5 inches, forecasters said. Areas in the Connecticut River Valley and the Berkshires will likely see 2 to 3 inches of rain within a six-hour timespan.

The weather service issued flood warnings just before 6 p.m. for much of Central and Western Massachusetts, saying that those living in flood-prone areas should be on alert for significant urban and small stream flooding. Locations that will experience flooding include Worcester, Springfield, Chicopee, Fitchburg, Northampton, Greenfield, Auburn, Russell, Montgomery, and Blandford, forecasters warned.

Luckily, the storm is moving at a fast clip, meaning the torrential rainfall won’t last too long.

Overnight, there is a small potential for severe weather, including an isolated thunderstorm, though the storm’s main threats are heavy downpours and damaging winds, forecasters said. It’s a long shot, but an isolated tornado coming from the southeastern edge of the storm is also not out of the question.

Winds will really only be a factor for the immediate South Coast, Cape Cod, and the islands, which could see 40- to 50 mile-per-hour winds late tonight into early Saturday, forecasters said.

Saturday won’t be a day to visit the beach — high surf and dangerous rip currents will be an issue along south-facing shorelines, thanks to the storm churning up the Bay State’s waters. The heavy rain will continue overnight, with temperatures holding steady in the mid-50s, Dunham said.


Saturday will start out rainy, with pockets of heavy rain popping up here and there.

However, things should start drying out by noon. There should even be some sunshine breaking through the clouds in the mid- to late afternoon, Dunham said. Expect highs in the lower 70s.

Despite its sloppy start, the weekend should end on a high note, with partly sunny skies, west winds, and highs in the upper 70s on Sunday.

The workweek will start out wet again, though, Dunham said, with showers possible Monday through Wednesday, though temperatures should be close to normal in the mid-70s.
