SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Little Egg Inlet to Sandy Hook, New Jersey * Long Island from East Rockaway Inlet to the eastern tip along the south shore and from Port Jefferson Harbor eastward on the north shore * New Haven, Connecticut to Merrimack River, Massachusetts including Cape Cod, Block Island, Martha's Vineyard, and Nantucket A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. For information on wind hazards north of the Tropical Storm Warning area, please see products from your local weather office. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 500 AM EDT (0900 UTC), the center of Tropical Storm Elsa was located near latitude 39.4 North, longitude 74.3 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, Elsa will pass through the eastern mid-Atlantic states early this morning, and move near or over the northeastern United States by late morning and this afternoon and tonight. 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, and 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. During the past couple of hours, a wind gust to 78 mph (126 km/h) was measured by a WeatherFlow site in Ludlam Bay, New Jersey, while a wind gust to 71 mph was observed in Beach Haven, New Jersey. These two wind reports appear to have been associated with nearby tornadoes. The estimated minimum central pressure is 1000 mb (29.53 inches), based on nearby surface observations. HAZARDS AFFECTING LAND ---------------------- Key messages for Elsa can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5, WMO header WTNT45 KNHC and on the web at www.hurricanes.gov/graphics_at5.shtml?key_messages. WIND: Tropical storm conditions are expected to continue along the mid-Atlantic coast early this morning. These winds will spread northward in the warning area over the northeastern states from late this morning into the afternoon. RAINFALL: Across northern New Jersey, Long Island, and southern and coastal New England...2 to 4 inches of rain with isolated totals up to 6 inches are possible through Friday, which could result in considerable flash and urban flooding. Isolated minor river flooding is also expected.
