Tropical Storm Arlene was a short-lived Gulf of Mexico storm that teased Florida residents and kicked off the official start to Hurricane Season.

T​he system was designated Tropical Depression Two based on a June 1st Hurricane Hunters mission. Another mission early the following day found tropical-storm-force winds, allowing the National Hurricane Center to upgrade the depression to Tropical Storm Arlene.

A​rlene was an odd southward-moving tropical storm in the Gulf. It was between an expansive ridge of high pressure over the Central U.S. and a weak trough over the adjacent Atlantic, which helped push the system equatorward.

A​rlene was a well-sheared system that probably shouldn't have been able to blossom, but did.

A​ quiet disturbance moved northeastward through the Gulf into the waters just off the western Florida panhandle in the last few days of May. This was an area that was hostile to tropical cyclone development: Strong west-to-east winds over the Gulf and cooler-than-average waters.

B​ut those relatively cooler waters may have allowed cyclonegenesis. Waters were just warm enough and skies aloft were just cool enough for thunderstorm growth, but not so much that robust thunderstorms would grow up into the jet stream.

A​rlene and its pre-genesis depression were able to fester literally under the effects of the strongest winds aloft. Should the storm have been any stronger, its cloud tops would have been any stronger.

A​s the system moved southward and into warmer water, shear increased around the storm and cloud tops began to be removed from Arlene. The system weakened in the southern Gulf

I​t happened one year ago. If this early occurring storm sounds like déjà vu, it's not your imagination.

In early 2022, a tropical disturbance tracked across South Florida producing flooding rain before it finally became Tropical Storm Alex east of the Florida coast.

U​nlike Arlene, what eventually became Alex had some remnant moisture and spin from a former hurricane, Agatha, in the Eastern Pacific Basin.

Alex eventually overcame both dry air and wind shear to become 2022's first storm of the season.
