The first named tropical weather system of the 2018 – subtropical storm Alberto - was located about 85 miles southeast of Cozumel, Mexico, sustaining winds of 40 miles an hour, Friday afternoon.

According to the Weather Channel, Alberto was moving eastward at 2 miles an hour in the western Caribbean Sea, and was expected to head north through the Gulf of Mexico over the Memorial Day weekend, bringing possibility of tornadoes, flash flooding, rip currents, strong winds and coastal flooding in the northern Gulf coast.

Although the center of the storm was located off the southern coast of Mexico's Yucatán Peninsula, there remained a possibility of it shifting to the western tip of Cuba overnight.

Hence, a tropical storm watch was issued for the Gulf coast from Louisiana to Florida, parts of Yucatan peninsula in Mexico, including Tulum, and western Cuba.

The National Hurricane Center defines a subtropical storm as “a subtropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) is 34 kt (39 mph or 63 km/hr) or more.” They have the potential to eventually develop into tropical storms and hurricanes.

Subtropical storm Alberto was officially announced a day after the National Oceanic and Atmospheric Administration (NOAA) released their hurricane season forecast for 2018. In the report, meteorologists expected an active Atlantic hurricane season with at least 10 to 16 major storms, with five to nine hurricanes, out of which, one to four could have sustained winds of at least 111 mph.

On Thursday, NOAA tweeted:

Effects

The northeastern portions of the Yucatan Peninsula and western Cuba are expected to receive 25 inches of rain, while four to eight inches and a maximum of 12 inches are possible across the Florida Keys and southern and southwestern Florida, CBS News reported.

Effects of the subtropical storm along the central Gulf Coast region and the southeastern United States are expected to begin during the weekend and continue into early next week.

The water could reach two to four feet above land from Horseshoe Beach in northern Florida to the mouth of Mississippi River, where a storm surge watch has been issued.

Chances of flooding would increase over the next week when the subtropical storm begins to slow down after it moves inland. Weather experts have warned rainfall could bring extreme flash floods and mudslides.

Areas like the western areas of Cuba and the eastern coast of Mexico's Yucatan Peninsula can experience surf swells that can lead to dangerous surf and rip current conditions. Similar weather conditions are also forecast for central and eastern U.S. Gulf Coast.

Also, a threat of tornadoes lingers from Sunday to early Tuesday near the northern Gulf Coast.
