MIAMI, Florida – NOAA’s National Hurricane Center issued a Public Advisory at 4 p.m. Eastern Standard Time on Thursday, November 12, 2020, due to the presence of Tropical Storm Eta that is tracking toward Florida’s west coast.

This is the first time an Atlantic Hurricane Season has reached the name Eta in the Greek Alphabet list.

Eta is the twenty-eighth named storm of the 2020 season which ties the record for the number of named storms set in 2005.

Tropical Storm Eta is located about 90 miles south-southwest of Charleston, South Carolina, and is moving to the northeast at 18 mph (30 km/h).

NHC forecasters say that a faster north-northeastward to northeastward motion is expected over the next couple of days.

On the NHC forecast track, Eta is expected to accelerate over the western Atlantic and move parallel to, but offshore of the Carolinas tonight and early Friday before heading well east of the Mid-Atlantic coast by late Friday.

Eta has maximum sustained winds near 40 mph (65 km/h), with higher gusts.

Little change in strength is forecast through early Friday.

Eta could re-intensify as a non-tropical cyclone late Friday or Friday night before becoming absorbed by a larger non-tropical cyclone on Saturday.

Tropical-storm-force winds extend outward up to 115 miles (185 km), mainly northeast through southeast of the center of the tropical cyclone.
