Arlene has weakened to a tropical depression as of late Saturday morning. The Air Force Hurricane Hunters have been investigating Arlene this morning winds have decreased to 30 kt or less. This weakening trend is due to strong vertical wind shear and dry air that has wrapped into the circulation, and continued weakening is forecast. If this trend continue, Arlene will be designated a remnant low by later today. The tropical depression is moving south-southeastward and will turn to the east later today as it inches closer to Cuba. While this system is moving away from Southwest Florida, it will likely increase scattered storms this afternoon.
What happened to Tropical Depression One?
You may have never heard about Tropical Depression One, because very few of us did. The news came on May 11, five months after a subtropical storm formed in the Atlantic but posed no threat to land.
The National Hurricane Center explained that through the course of typical re-assessment of weather systems, NHC hurricane specialists determined that an area of low pressure that formed off the northeastern coast of the United States in mid-January should be designated as a subtropical storm. Specific information on the justification for the subtropical storm designation will likely be issued during the next couple of months.
The January subtropical storm is being numbered as the first cyclone of 2023, which is why the depression in the Gulf of Mexico that developed on June 1 was designated as Tropical Depression Two.
