Hermine Update: Tropical Storm Conditions Expected in Suffolk, Flooding Concerns Islandwide

Yes, Hermine is still hanging around with a tropical storm warning remaining in effect for Suffolk County and some minor flooding concerns for the entire island.

As of 7 a.m. Tuesday, the post-tropical cyclone was about 100 miles southeast of Montauk, packing maximum sustained winds of 65 mph. The storm is moving to the west at about 8 mph. A decrease in forward speed is expected later Tuesday, and Hermine will likely become nearly stationary Tuesday night. A turn toward the northeast is forecast to occur on Wednesday.

Wind gusts reached tropical storm-force (39-73 mph) on the East End of Long Island on Monday, and the odds of tropical storm-force winds across all of Long Island on Tuesday have increased again as Hermine has tracked closer to the coast than expected.

As of 9:44 a.m. Tuesday, more than 500 PSEG Long Island customers were without power, but that's well below the more than 2,000 who lost power, mainly on the East End, Monday night. See PSEG's outage map here.

There have been no reports of major flooding on the island due to Hermine, but a storm surge threat along coastal areas in Suffolk (tides could reach 1-2 feet above ground) will remain on Tuesday and Wednesday before Hermine finally heads out to sea.

In Nassau County, a coastal flood advisory will be in effect from 10 a.m. to 3 p.m. on Tuesday.

There may be minor flooding of the most vulnerable shore roads in Nassau due to the height of storm tide or wave splash-over, the National Weather Service said.

Dangerous rip currents, high surf and beach erosion are forecast until Wednesday across Atlantic Ocean shores.

Once Hermine departs Wednesday night, get ready for a little late-summer heatwave. Temperatures are expected to approach 90 degrees on parts of the island Thursday through Sunday.
