Oct 17: Coastal Storm Detected!

An upper level low pressure disturbance will move from Canada across the Great Lakes and stall out near the benchmark (70N/40W) next week. Impacts should be felt as early as Tuesday evening. There is uncertainty as to when it will clear out. My best guess right now is between Thursday evening and Friday morning. Once the low makes it into the Atlantic Ocean it will be met and enhanced by moisture and energy associated with the back (west) side of high pressure before moving away and out to sea.

This is not a dangerous storm by any means…a run of the mill October coastal if you will. Low pressure intensity is not that impressive and neither are expected rainfall amounts. This is more of a prolonged nuisance event that could feature minor to moderate rain and wind, minor coastal flooding and beach erosion. This is the free public version of the European model (courtesy of WeatherBell Analytics) showing wind speed in knots at the 850mb level (~5000 ft above sea level) 144 hours out (Thursday morning at 8AM):

Even though there is decent model consensus at this point, we’re still 5-6 days away. That’s plenty of time for start and end times to shift left or right on the expected timeline. I’ll be closely monitoring this system very closely as it evolves and approaches. You know where to find the latest info! Be safe! JC
