Quick update on Gamma with 2 more potential systems and Long Island weather:


  • Tropical Storm Gamma has maximum sustained winds of 45 mph, and it will make landfall in the Yucatan Peninsula later today. The main impact will be tremendous rainfall that could approach 15 to 20 inches in some areas.

  • The system behind Gamma has a 40% chance of tropical development, according to the National Hurricane Center. It looks like it has a chance to eventually head towards the central Gulf coast states, but possibly only as a tropical storm.

  • There is a 3rd area to watch in the Atlantic, but it doesn't look like anything to worry about, and the NHC is giving it a 10% chance of tropical development.

Long Island forecast:

Today: Mostly sunny with highs in the mid to upper 60's.

Tomorrow: Mostly sunny with increasing clouds by late afternoon and evening with highs in the mid to upper 60's.

Monday: Cloudy with a 50% chance of showers, mostly in the morning, with highs in the low 60's. The best chance of showers is in Suffolk. 

Tuesday: Mostly sunny with highs in the mid to upper 60's.

Wednesday: Partly cloudy with highs in the low 70's. A cold front coming through at night should bring some showers.

Thursday: Mostly sunny and breezy with highs mostly in the mid 60's.
