Meteorological History

220px-Alberto 2018 track

On May 21st, a low pressure system began to be monitored in the Western Caribbean. The system drifted into the Yucatan, slowly developing despite fairly unfavorable conditions. The storm would later develop sufficiently to be named Subtropical Storm Alberto on May 25th. The storm despite it's naming, the storm was still unorganized. The next day, Alberto developed a better circulation around a better defined center.

Alberto would continue a fairly Northward path in the days following. During this time, a large group of it's outer rainbands massed around it's Eastern quadrants, bring heavy rainfall to Florida and Cuba during this time. On May 28th, Alberto reached it's peak intensity of 65 mph. Dry air weakened it abruptly back down to 45 mph before making landfall on the Northwestern sliver of Florida.

Alberto would continue Northward, slowly weakening for the following days. On May 30th, Alberto finally made a Tropical transition over Tennessee. That same day, Alberto became Post-Tropical over Michigan. The next day, Alberto would dissipate over Lake Huron.
