A wet and windy Monday is in store for the Boston area, with pockets of heavy rain, possible thunderstorms, and damaging wind gusts up to 60 mph expected throughout the day. A flood watch is in effect due to the persistent rainfall and recent snow melt, while a wind watch is also in place for the Boston metro area and Cape Cod.
Why it matters
The combination of heavy rain and strong winds could lead to localized flooding, power outages, and downed trees or branches, posing risks to public safety and infrastructure. The storm system is also impacting the region's transition into spring, with cooler than normal temperatures expected for the week.
The details
The rain is expected to start in the morning and continue through the evening, with a brief dry period possible late morning and early afternoon. Pockets of heavy rain and a few rumbles of thunder are possible, especially if any sunshine breaks through during the dry spell. The flood watch is in effect from 5 a.m. Monday to 8 a.m. Tuesday due to the persistent rainfall and recent snow melt, which could lead to ponding on roads, high water in low-lying areas, and rising river levels. As the rain becomes less widespread, damaging wind gusts of 60 mph or higher are possible, particularly in the evening hours. A wind watch is in place from 5 a.m. Monday to 6 a.m. Tuesday for the Boston metro area, South Shore, and Cape Cod.
