DISCUSSION AND OUTLOOK
At 500 AM EDT (0900 UTC), the center of Tropical Storm Elsa was
located near latitude 33.4 North, longitude 81.3 West. Elsa is
moving toward the northeast near 18 mph (30 km/h), and this general
motion is expected to continue with an increase in forward speed
during the next couple of days. On the forecast track, Elsa will
move over South Carolina and North Carolina today, pass near the
eastern mid-Atlantic states by tonight, and move near or over the
northeastern United States on Friday and Friday night. The system
should move over Atlantic Canada by Friday night and Saturday.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Some re-strengthening is possible tonight and Friday while the
system moves close to the northeastern United States. Elsa is
forecast to become a post-tropical cyclone Friday night or Saturday.
Tropical-storm-force winds extend outward up to 115 miles (185 km)
mainly over water to the southeast of the center. The NOAA station
at Folly Island, South Carolina, recently reported sustained winds
of 38 mph (61 km/h) and a wind gust of 46 mph (74 km/h).
The estimated minimum central pressure is 1007 mb (29.74 inches).
