The storm named Hermine continues to influence our weather Monday, but the impact to the area won’t be significant.
Hermine is no longer a tropical system, rather it’s a post-tropical one, meaning the storm has lost many of its tropical characteristics and in many ways resembles a winter type of storm.
As is the case in winter, there will be some beach erosion during the time of high tide, around 2 a.m and 2 p.m. The persistent wind coming from the east creates larges swells, which move large amounts of sand from the beaches.
We do know the storm won’t create large damage or massive flooding, but it is still an ocean storm with a good deal of wind and rain.
Since Cape Cod and the Islands are closest to the storm, they will bear the brunt of its effects and see the most wind and rain. Even their rainfall totals will remain under 2 inches, not a number which promotes flooding beyond some street-type issues during the heaviest downpours.
In and around the Greater Boston area, rainfall will be limited.
The best chance of getting to the rain shield will be areas inside of I-495, but really it’s those areas within the Route 128 belt and east of I-95 which may see a quarter-inch of rainfall.
The loop below from one of the models shows showers rotating west across the region through mid-week.
This amount of rainfall is not only small, but won’t be enough to quell the drought. If you don’t see any rain, the cloud shield will thicken throughout Monday, so there won’t be much, if any, sunshine either.
Monday night and Tuesday bring the best chance for showers with the same pattern of coverage in play. In other words, the further west you live, the drier it will be. Showers will remain in the forecast through Wednesday when the storm finally either moves too far away or falls apart. There is still some question how Hermine will actually end.
As the storm departs Tuesday night and Wednesday, warmer and more humid air will push back into the region. Temperatures will make it into the 80s by Wednesday afternoon away from the coast and start heading for the 90s Thursday and Friday. This is 10 to 15 degrees above normal for early September.
