NOAA: Tropical Depression Gamma Dissipates

UPDATE: Tropical Depression Gamma has dissipated.

MIAMI, Florida – NOAA’s National Hurricane Center issued a Public Advisory at 5 p.m. Eastern Daylight Time on Monday, October 5, 2020, due to the presence of Tropical Depression Gamma (formerly Invest 91L, Tropical Depression 25, and Tropical Storm Gamma) over the southern Gulf of Mexico.

Tropical Depression Gamma Projected Path

Tropical Depression Gamma is located about 135 miles northwest of Cozumel, Mexico, and is moving to the southwest at 5 mph (7 km/h).

NHC forecasters say that a southwest or west-southwest motion is expected to continue through Wednesday morning.

On the official NHC forecast track, the center of the depression should move inland over the northwest coast of the Yucatan peninsula Tuesday and remain over the northern portion of the peninsula and dissipate Wednesday.

After the remnants of Gamma make landfall, dissipation is likely to occur Wednesday as larger Tropical Storm Delta approaches the Yucatan Channel.

The NHC forecast track is basically an update of this morning’s package and is based on the various multi-model consensus aids.

Tropical Depression Gamma has maximum sustained winds of 35 mph (55 km/h), with higher gusts.

Gradual weakening is forecast, and Gamma is expected to degenerate into a post-tropical remnant low tonight and dissipate over the northern portion of the Yucatan peninsula Wednesday.

September 10 was the peak of the Atlantic hurricane season, where tropical cyclone activity significantly increases. But hurricane season still remains at an increased level of activity through the first half of October, according to NOAA and the National Weather Service’s historical data.

NOAA and Colorado State University forecast an “extremely active” 2020 Atlantic Hurricane Season, which runs from June 1 through November 30.
