DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Elsa was
located by surface and radar data over eastern Long Island near 
latitude 41.0 North, longitude 72.1 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 eastern Long Island and the coast of southern New 
England through this afternoon, and then offshore the northeastern 
United States coast by this evening. 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 today. Gradual
weakening is forecast to occur over the weekend. Elsa is forecast
to become a post-tropical cyclone this afternoon.
 
Tropical-storm-force winds extend outward up to 175 miles (280 km)
from the center. A WeatherFlow site near Jones Beach, New York
recently reported a wind gust to 47 mph (76 km/h) and a WeatherFlow
site near Block Island Jetty observed a sustained wind of 39 mph
(63 km/h) with a gust to 54 mph (87 km/h).
 
The estimated minimum central pressure based on data from NOAA
buoy 44025 is 1000 mb (29.53 inches).
