Major rainstorm ahead

A storm centered over the Ohio valley will very slowly move up the eastern seaboard over the next few days bringing the area soaking rain and wind. During the day on Monday the heaviest rain will be centered around Worcester and points west. However, during the evening the heaviest rain will come into the Boston area and last through most of Tuesday. The wind will also pick up during this time with gusts over 40 MPH along the coast, including Boston. This rain will create major river, urban and basement flooding over most of the area by Wednesday. BE PREPARED WITH AN EVACUATION PLAN IF YOU ARE PRONE TO FLOODING. Please avoid all low lying roads starting Tuesday morning commute including the J-way and Storrow drive. 

Alert: A flood watch is in effect for all of the area, except the Cape. I expect this to be upgraded to a Flood Warning at some point during the storm.
