On Friday morning, the center of the disorganized storm was 170 miles south-southeast of Myrtle Beach, S.C., and was virtually stationary in its movement. Ana’s maximum sustained winds are 45 mph, and it is forecast to remain at the intensity of a subtropical or tropical storm for the next several days as it lingers off the South Carolina coast.
A tropical storm watch (yellow in the image below) has been issued for the southeast coast from Cape Lookout, N.C., down to Edisto Beach, S.C.
Ana’s biggest impact to the coast will be periods of heavy rain. Coastal locations will also experience some gusty winds over gale-force at times, as well as increased surf and beach erosion. Dry air from the eastern United States has been getting wrapped into the storm’s circulation, which has greatly limited the development and the rainfall coverage.
The graphics below highlight the five-day precipitation forecast and the five-day probability of tropical-storm-force winds (39-plus mph). Areas toward the coast could see more than 2 inches of rain from Ana. At this time, South Carolina coastal areas have the highest chance of seeing at least tropical-storm-force winds.
Ana could transition to a tropical storm in the coming days, but to the practical observer on the ground, the technical classification will not change the storm’s effects. The bulk of the impacts will be limited to coastal South and North Carolina, but as the system weakens over land and heads back out to sea, some breezy winds and remnant moisture could potentially make their way up to the Mid-Atlantic, including the D.C. area on Monday.
