MOBILE, AL - The National Hurricane Center has named the disturbance in the southeastern Gulf of Mexico as Sub-Tropical Storm Alberto. At this time, it is still too early to determine what direct impacts the system might have on Mobile County and Southwest Alabama, but elevated winds, heavy rain and dangerous rip currents are expected for Memorial Day weekend.

The difference between a subtropical storm and tropical storm is core temperature, according meteorologists. Subtropical storms have slightly lower core temperatures than tropical storms. Alberto could transition to a tropical storm.
