Update on Tropical Depression 26 (future Hurricane Delta) and Long Island weather:
Tropical Depression Twenty-Six, which used to be Invest 92L and then Potential Tropical Cyclone Twenty-Six, will be upgraded to Tropical Storm Delta today. It's expected to become a Category 2 hurricane with maximum sustained winds of 105 mph. It will generally head towards the central Gulf coast, but it will be weakening on approach due to increased wind shear and cooler waters closer to the coast. It will probably make landfall as a strong Cat 1 on Friday.
Tropical Storm Gamma will be steadily weakening, and it will be moving slowly in the southern Gulf near and along the west coast of the Yucatan Peninsula.
