Good morning, We wanted to give everyone a heads up on the potential for locally heavy rainfall today which may lead to a risk of localized urban and poor drainage flooding. Details follow below. *What:* - Localized heavy rainfall with amounts of 2+ inches in a 6 hour period - Urban and poor drainage flooding possible if these amounts are realized *Where:* - The best chance will be south of the Mass Pike, particularly across eastern CT, RI and portions of southeast MA. *When:* - Mainly this afternoon into early evening - Heavy rainfall may impact the afternoon commute *Uncertainty:* - There is uncertainty with respect to where the axis of heavy rainfall will set up. The location may still shift to the north or south We have attached graphics showing our expected rainfall, worst case scenario rainfall, and the probability of greater than 2 inches of rainfall. As always, if you have any questions or concerns, please reach out to us any time.
