HOLT, Fla., Aug. 19, 2022—Invest 99 located in the southwestern Gulf of Mexico has developed into Potential Tropical Cyclone Four.

The National Hurricane Center is forecasting PTC4 to become Tropical Storm Danielle tonight or tomorrow.

This is only the third system of the 2022 Atlantic Hurricane Season. Previous years saw storm development begin prior to the June 1 seasonal start and go on to become record-setting seasons. This year is the first since 2014 not to have a pre-season named storm.

According to the NHC, the low pressure system became better organized during the past 24 hours. An Air Force Reserve Hurricane Hunter mission found wind speeds to be 35 mph, although it does not yet have a well-defined center of circulation.

PTC4 is forecast to develop further and make a Mexican landfall as a tropical storm tomorrow night with estimated 45 mph winds. Tropical storm warnings have been issued for portions of the northeastern Mexican and south Texas coasts.

The system will weaken after landfall, and by Wednesday, it is forecast to be absorbed into a larger low pressure area forming over western and northern Texas, according to the NHC.

Note: This story was updated to correct the name of the system from Tropical Depression Four to Potential Tropical Cyclone Four.
