Isaias Will Bring Heavy Rain & Strong Winds To Western & Central Mass Tuesday Afternoon & Night

Tropical Storm Isaias, which is curently located off of the coast of Georgia and northeast Florida will play a huge part in our weather for Tuesday afternoon and Tuesday night. The tropical storm is expected to start bringing some intermittent light to moderate rain into the region late tonight and Tuesday morning. The rain is expected to increase in intensity across Western Mass by late Tuesday afternoon with heavy rain expected for several hours on Tuesday night along and west of I-91. The track of Isaias will bring the center of the storm right across Western Mass. Since this is a lopsided storm, the heavy rain will fall to the west of the storm track and the strong winds will occur to the east of the storm track. Forecast Impacts: Heavy Rain: The heaviest rainfall amounts of up to 3 to 5 inches are expected west of I-91 and especially in the Berkshires during Tuesday afternoon and Tuesday night. Further east, the rainfall amounts are expected to be much lower with up to 1 to 2 inches possible across the I-91 corridor eastward to about the I-395/I-190 corridor. Along I-290 and I-495, less than 1 inch of rain is expected. This means that the highest flood threat will be in the Berkshires with flash flooding a possibility. Strong Winds: Right now, it looks like strong winds will be the much bigger issue with this storm rather than heavy rain. Wind gusts of up to 50 to 60 mph are expected across much of Western and Central Mass for several hours beginning Tuesday evening and continuing until just after midnight Tuesday night. These strong wind gusts will have the potential of bringing down trees and power lines leading to at least some scattered power outages. Isaias is expected to move out very quickly by late Tuesday night leaving us with at least a partly sunny and much calmer day on Wednesday. I am keeping extremely close watch on the progress and forecast of Isaias and will have additional updates for you as needed.
