DISCUSSION AND OUTLOOK
----------------------
At 200 AM EDT (0600 UTC), the center of Tropical Storm Elsa was 
located near latitude 38.3 North, longitude 75.7 West.  Elsa is 
moving toward the northeast near 25 mph (41 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 
pass through the eastern mid-Atlantic states this morning and move 
near or over the northeastern United States this afternoon and 
tonight. The system should move over Atlantic Canada by late tonight 
and Saturday.
 
Maximum sustained winds remain near 50 mph (85 km/h) with higher 
gusts.  No significant change in strength is expected through today, 
and Elsa is forecast to become a post-tropical cyclone by tonight.
 
Tropical-storm-force winds extend outward up to 160 miles (260 km) 
mostly southeast of the center.  NOAA buoy 44009 near the mouth of 
Delaware Bay recently measured a sustained wind of 45 mph (72 km/h), 
gusting to 54 mph (87 km/h).
 
The estimated minimum central pressure is 1002 mb (29.59 inches),
based on nearby surface observations.
