located near latitude 31.7 North, longitude 77.4 West. The storm has
been meandering today, but is expected to begin a north-

The estimated minimum central pressure is 1001 mb (29.56 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are expected within the warning
area, and possible within the watch areas, by Saturday evening.
STORM SURGE: The combination of storm surge and the tide will cause
normally dry areas near the coast to be flooded by rising waters.
The water could reach 1 to 2 ft above ground at times of high tide
in coastal areas from Cape Hatteras, North Carolina southward
through South Carolina. For information specific to your area,
please see products issued by your local National Weather Service
RAINFALL: Ana is expected to produce rainfall accumulations of 2 to
4 inches, with isolated amounts of 6 inches, over eastern portions
of North Carolina and South Carolina through the weekend.
SURF: Swells generated by Ana are affecting portions of the
southeastern U.S. coast. These swells will likely cause life-
threatening surf and rip currents. Please see statements issued by
your local National Weather Service forecast office.
