Alberto formed out of a broad area of low pressure at the surface that was located over and around the Yucatan Peninsula. Because the area of low pressure was under the influence of a nearby upper-level trough, Alberto was designated as a subtropical storm by the National Hurricane Center (NHC) on the morning of Friday May 25th, which is rather unusual as most subtropical storms form at higher latitudes. The storm initially formed just east of the Yucatan Peninsula. A large subtropical ridge over the southwestern Atlantic steered Alberto on a northward track, and the storm brushed the far

At 10:00 AM CDT today the National Hurricane Center (NHC) upgraded low pressure center (90L) to Subtropical Storm Alberto. Alberto moved over the waters of the northwestern Caribbean Sea.

The second tropical cyclone in less than a week has formed in the western Arabian Sea early on May 22, 2018. This tropical cyclone called MEKUNU is intensifying as it heads toward Oman.

This will make it the equivalent of a category two hurricane on the Saffir-Simpson hurricane wind scale. Tropical cyclone MEKUNU follows on the heels of destructive and deadly tropical cyclone SAGAR that just made landfall over northwestern Somalia a few days
