The flood watch highlights the risk of localized flooding in areas experiencing heavy downpours. Communities in eastern Massachusetts and Connecticut, including Springfield, Hartford, and MetroWest, are most at risk. While Southeast Massachusetts is expected to see less rain, residents should remain cautious. Gusty winds along the coast may also pose minor risks to outdoor activities. The storm system's slow movement could prolong rainfall, increasing the likelihood of water accumulation in low-lying areas. (Source: NBC10 Boston)
