A major storm is on the way for tonight and tomorrow as Tropical Storm Philippe is set to race from Florida to Maine in under 24 hours, while merging with a powerful extratropical cyclone. If you’re interested in the meteorology behind this system, I broke it all down in last night’s weather.us blog discussion. I’ll have more updates for weather.us on Twitter and on the blog through the day today, this update will give a quick synopsis of what to expect for Western Maine and New Hampshire.
Rain will continue to develop from southwest to northeast today as tropical moisture surges into the region. SE winds will also pick up as low pressure develops to our west. The worst of the weather will hold off until early tomorrow morning, however.
Tomorrow morning, the remnant core of TS Philippe will be making landfall in Maine, near Portland. Torrential rains (shown above in the simulated radar image) will cause flash flooding issues, and wind gusts near or possibly over hurricane force will result in downed trees and power outages.
Temps will be seasonably mild today, in the upper 50’s to low 60’s.
Rain will clear out midday tomorrow with gusty westerly winds bringing drier air into the region. Westerly winds could gust over 45 mph tomorrow afternoon, continuing the power outage threat.
