Magic number:3

Another major nor'easter is headed our way for the first half of the week. It will bring heavy rain, strong winds and more flooding. If we pick up more than 3 inches of rain then the rivers will once again go over their banks. Unfortunately, I now expect 3-6 inches of rain for Monday thru Tuesday night and into Wednesday morning. Jamaica Pond and the Muddy river will once again need to be watched for significant flooding. I also expect flooded basements, so make sure to take valuables upstairs tomorrow before the storm hits. Great weather will follow the storm at the end of the week with sunny skies and temps climbing into the 70's! 

Alerts: A Flood Watch is in effect for the entire area. I expect this will be upgraded to a flood warning at some point during the storm.
