Tropical Depression Twenty-Five has strengthened into Tropical Storm Gamma on Friday night.
This is the 25th tropical cyclone of the 2020 Atlantic Hurricane Season and the earliest 24th named storm in Atlantic history. The previous record for the 24th named storm was Beta, on October 27th, 2005. The last (and only) time Gamma was used in the Atlantic was on November 15th, 2005.
This tropical cyclone is not forecast to impact Trinidad, Tobago, or the Lesser Antilles. This system spawned from Tropical Wave 52 which impacted our area last weekend.
At 8:00 PM AST, the center of Tropical Storm Gamma was located near latitude 18.8 North, longitude 85.8 West. Gamma is moving toward the northwest near 9 mph (15 km/h), and a gradual turn toward the north-northwest with a decrease in forward speed is expected over the next couple of days. On the forecast track, the center of the tropical cyclone should be near the northeastern Yucatan Peninsula on Saturday.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Slow strengthening is forecast during the next few days. The estimated minimum central pressure based on data from the Air Force Hurricane Hunters is 1000 millibars.
