Alberto - the first named storm of the 2018 hurricane season - prompted Florida, Alabama and MS to launch emergency preparations.
A subtropical storm has a less defined and cooler center than a tropical storm, and its strongest winds are found farther from the center. There is also a high risk of risky rip currents and extremely rough bay waters.
A CNN image released on May 26, 2018, shows where Subtropical Storm Alberto is likely to make landfall on Monday between New Orleans and Destin, Florida, before moving into MS and Alabama by Tuesday. According to a report by CNN, the storm has already caused dreary weather for Memorial Day weekend all along the Gulf coast. The tropical system became a subtropical storm Friday, the hurricane center said.
The slow-moving system is expected to pack heavy rains and winds over the Memorial Day weekend.
Along the coast three to six inches of rain are expected. However, the storm should not be taken as an indicator of how this hurricane season will play out, he said.
Forecasters are expecting the strongest winds, which could be from 20-25 miles per hour with higher gusts, to be confined to areas along and south of I-85 on Monday night.
At 7:30 p.m. EDT Sunday, Alberto was centered about 195 miles (315 kilometers) west of Tampa and had maximum sustained winds of 65 mph (100 kph) - up from 50 mph (85 kph) earlier.
