DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Elsa was
located near latitude 40.2 North, longitude 73.1 West. Elsa is
moving toward the northeast near 31 mph (50 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, the 
center of Elsa will move near or over eastern Long Island and the 
coast of southern New England today, and then offshore the 
northeastern United States coast by late this afternoon.  The 
system should move over Atlantic Canada by late tonight and 
Saturday.
 
Maximum sustained winds are near 50 mph (85 km/h) with higher
gusts. No significant change in strength is expected through today.
Elsa is forecast to become a post-tropical cyclone by tonight.
 
Tropical-storm-force winds extend outward up to 160 miles (260 km)
from the center. NOAA buoy 44066 located about 85 miles (140 km) 
east of Long Beach, New Jersey recently measured a peak one-minute 
sustained wind of 45 mph (72 km/h) and a gust to 49 mph (80 km/h). 
 
The estimated minimum central pressure is 1000 mb (29.53 inches),
based on nearby surface observations.
