It’s possible that parts of Rhode Island and eastern Massachusetts receive less than one inch of rain. Minor coastal flooding may impact south coastal Rhode Island and Massachusetts during high tide Tuesday evening. Inundation would be less than one foot above ground level if it were to occur. Rough surf and an increased risk of dangerous rip currents should affect south coastal beaches Tuesday and at least into Wednesday.

Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow.
Driving conditions become hazardous. Some road and bridge closures. Elsewhere across southern New England, little to no impact is anticipated.
Prepare for a tornado event having possible limited impacts across western Massachusetts and north central Connecticut.

Now is the time to check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business. When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes extend well away from the center of the storm. Check on those who may not be fully aware of the situation or who are unable to make personal preparations.
