Subtropical Storm Alberto was the first storm of the 2018 Atlantic hurricane season. Alberto developed on May 25 from a tropical disturbance that had been drifting around near the Yucatán Peninsula. Strong wind shear limited strengthening as the storm meandered over the northwestern Caribbean Sea and the Gulf of Mexico, where it passed close to the western end of Cuba. Alberto began to gradually strengthen under more favorable environmental conditions. Early on May 28, Alberto reached its peak intensity with maximum sustained winds of 65 mph (100 km/h) and a minimum pressure of 990 mbar (hPa; 29.23 inHg). Afterwards, however, dry air caused Alberto to weaken before it made landfall near Laguna Beach, Florida, with winds of 45 mph (75 km/h). Alberto continued to weaken slowly while traversing Alabama, before leveling off in intensity and transitioning to a tropical depression over Tennessee. Eventually, Alberto weakened once again and became post-tropical over Michigan early on May 31.
