Localized flash flooding poses a significant risk, especially in areas with poor drainage or those still saturated from previous rainfall. Roadway flooding has already caused temporary closures, such as on Merriam Avenue in Leominster and Fitchburg. Gusty winds, particularly in thunderstorms, could lead to minor damage or disruptions. Residents in affected areas should remain vigilant, especially during periods of heavy rain, and avoid driving through flooded roads. The risk of additional storms later in the week could exacerbate already saturated conditions, increasing the potential for further flooding.
