Tropical Storm Ana was the earliest tropical cyclone in the Atlantic basin to make landfall in the United States on record. Ana formed as a subtropical cyclone and later strengthened to a peak intensity of 60 mph. Ana was the earliest named storm in the Atlantic since 2003's storm of the same name, which formed in late April.

Meteorological History

On May 3, the National Hurricane Center noted the possibility of subtropical or tropical development north of the Bahamas over the coming days from a decaying cold front. By May 7, the cyclone began to exhibit signs of organization, and at 00:00 UTC on May 8, the system was designated Subtropical Storm Ana after a reconnaissance aircraft identified a sufficiently well defined circulation and winds of tropical storm force.

Ana began to move slowly north-northwestward as it approached the United States coastline. Eventually, it became nearly stationary and began to strengthen. Early on May 9, Ana strengthened to its peak intensity of 60 mph and transitioned into a fully tropical cyclone shortly thereafter. Later that day as Ana approached land, it began to weaken, despite its structure increasingly resembling a typical tropical cyclone. Around 10:00 UTC on May 10, Ana made landfall near North Myrtle Beach, South Carolina, as a tropical storm with maximum sustained winds of 45 mph. Ana weakened to a tropical depression later that day. On May 11, Ana weakened into a remnant low, and advisories began to be initiated by the Weather Prediction Center instead of the National Hurricane Center at this time. On May 12, the remnant low associated with Ana dissipated.


Ana's impact was fairly minimal. Although it did bring heavy rains to the Southeastern U.S. in Mother's Day 2015, it caused minimal damage. However, it did cause 2 fatalities.
