Tropical Storm Isaias Public Advisory Number 31
2020-08-04 22:45:16| National Hurricane Center (Atlantic)
Issued at 500 PM EDT Tue Aug 04 2020 000 WTNT34 KNHC 042045 TCPAT4 BULLETIN Tropical Storm Isaias Advisory Number 31 NWS National Hurricane Center Miami FL AL092020 500 PM EDT Tue Aug 04 2020 ...ISAIAS RACING NORTH-NORTHEASTWARD ACROSS EASTERN NEW YORK... ...STRONG GUSTY WINDS...HEAVY RAINFALL...AND THE THREAT OF TORNADOES WILL SPREAD NORTHWARD ACROSS SOUTHERN AND CENTRAL NEW ENGLAND... SUMMARY OF 500 PM EDT...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...42.7N 74.2W ABOUT 20 MI...35 KM W OF ALBANY NEW YORK MAXIMUM SUSTAINED WINDS...65 MPH...100 KM/H PRESENT MOVEMENT...NNE OR 20 DEGREES AT 40 MPH...65 KM/H MINIMUM CENTRAL PRESSURE...995 MB...29.39 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The Tropical Storm Warning has been discontinued south of Manasquan Inlet, New Jersey, including all of the Chesapeake Bay, the Tidal Potomac River, and Delaware Bay. The Tropical Storm Warning has also been discontinued north of Stonington, Maine. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Manasquan Inlet New Jersey to Stonington Maine * Long Island and Long Island Sound * Martha's Vineyard, Nantucket, and Block Island A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 6 to 12 hours. 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 PM EDT (2100 UTC), the center of Tropical Storm Isaias was located by NOAA Doppler weather radars and surface observations near latitude 42.7 North, longitude 74.2 West. Isaias is moving toward the north-northeast near 40 mph (65 km/h), and this general motion is expected through tonight. On the forecast track, the center of Isaias will continue to move farther inland over eastern New York and Vermont this afternoon and evening, and over southern Canada tonight. Data from Doppler weather radars along with surface observations indicate that maximum sustained winds have decreased to near 65 mph (100 km/h) with higher gusts. Gradual weakening is expected this afternoon and evening, followed by a faster rate of weakening tonight. Isaias is forecast to become post-tropical tonight or early Wednesday. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. During the past hour, a NOAA NOS observing site at Sandy Hook, New Jersey, reported a sustained wind 41 mph (67 km/h) and a gust to 50 mph (80 km/h). Wind gusts in excess of 50 mph (80 km/h) have also been reported at multiple sites in southeastern New York, Connecticut, Rhode Island, and Massachusetts during the past hour. The estimated minimum central pressure based on surface observations is 995 mb (29.39 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Isaias can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml. STORM SURGE: The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Sandy Hook NJ to Martha's Vineyard MA including Long Island Sound, Block Island Sound, Narragansett Bay, Buzzards Bay, and Vineyard Sound...1-2 ft WIND: Widespread tropical-storm conditions are expected in the tropical storm warning area in eastern New York, Long Island, and southern New England, with wind gusts to hurricane force possible. These winds could cause significant tree damage and power outages. Tropical storm conditions are expected to reach southern New England by late afternoon, and reach northern New England tonight. Gale-force winds are expected to spread into southeastern Quebec tonight and Wednesday. See products issued by Environment Canada for more information. RAINFALL: The following rainfall accumulations are expected along and near the track of Isaias: Eastern New York into Vermont: 2 to 4 inches, isolated maximum totals 6 inches. Western Connecticut, western Massachusetts, New Hampshire and western Maine: 1 to 3 inches. Southern Quebec: 1 to 3 inches. Heavy rainfall near the path of Isaias, through the Hudson River Valley, is likely to result in flash flooding, particularly through urban areas and the surrounding terrain of the Catskills, Adirondack and Green Mountain Ranges through Tuesday night. Scattered minor to moderate river flooding is likely across portions of the Mid-Atlantic. Quick-responding rivers in the Northeast will also be susceptible to minor and possible moderate river flooding. TORNADOES: A couple of tornadoes are possible across southern New England late this afternoon. A risk for tornadoes may continue and spread across parts of northern New England through this evening. SURF: Swells generated by Isaias will spread northward along the mid-Atlantic and Northeast coasts of the United States today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 800 PM EDT. Next complete advisory at 1100 PM EDT. $$ Forecaster Stewart
