MASSACHUSETTS EMERGENCY MANAGEMENT AGENCY
SITUATIONAL AWARENESS STATEMENT #9
DATE: September 5, 2016
TIME: 6:30 AM
SUBJECT: Tropical Storm Hermine
Hermine remains a post-tropical storm approximately 260 miles south of Nantucket with 70 mph sustained winds. Tropical Storm Warnings remain in effect from Watch Hill to Sagamore Beach, MA, to include Barnstable, Dukes, Nantucket, Southern Bristol, and Southern Plymouth Counties, near shore and coastal waters, and southern offshore waters. The primary concern continues to be the wind threat associated with this storm and associated windfield. The primary wind threat will occur from 10 AM this morning to 8 PM this evening. There is a low risk for a secondary surge of gusty winds late Tuesday into early Wednesday across the Cape and Islands.
Forecast and Impacts:
Hermine is expected to continue moving east-northeast before turning more northerly today, followed by a slow northward to northwestward motion tonight and tomorrow. The center of Hermine will move slowly offshore of the mid-Atlantic coast over the next couple of days. The wind threat from Hermine is forecast to arrive in two pulses, with the strongest pulse between this morning and early afternoon with 30-50 mph wind gusts focused on the immediate south coast/islands, strongest between 10 AM and 8 PM. Scattered tree and power outages are possible along the south coast, Cape and Islands, where tropical storm force winds are most likely today. Drought exhausted trees could fall more easily. Isolated downed tree limbs are possible across eastern Massachusetts with 25 to 35 mph wind today. High surf and
dangerous life threatening rip currents will linger into mid-week, especially along east and south facing exposed beaches along the south coast, Cape Cod and Islands.
Scattered showers will develop from southeast to northwest today and continue at times into Tuesday. Rainfall amounts will generally be less than .50 inches, except for the far southeast New England coast that may see as much as 1.50 inches of rainfall through Tuesday. A 1-2 foot storm surge is possible later today and this evening with no significant impact expected other than some minor beach erosion.
Where There Remains Uncertainty:
· Uncertain if 40 mph wind gusts make it northwest of the Cape and Islands today.
· Whether a weaker, but second surge of gusty winds affect the Cape and Islands late Tuesday into early Wednesday.
