The primary risks include heavy rain, flash flooding, and strong wind gusts. Flooding is a significant concern for areas under the flood watch, particularly in western Massachusetts and Connecticut. Urban areas and locations with poor drainage are especially vulnerable to water accumulation. Wind gusts of up to 35 mph could cause minor damage, particularly in coastal areas like the Cape and Islands. Residents in Greater Boston and surrounding regions should prepare for potential disruptions due to heavy rain and localized flooding (NBC Boston, 2026-07-28).
