What the computer models are showing for TC 08L (Henri)

SLOW-MOVING HENRI EXPECTED TO CONTINUE TO PRODUCE HEAVY RAINFALL AND FLOODING ACROSS PORTIONS OF SOUTHERN NEW ENGLAND AND THE NORTHERN MID-ATLANTIC STATES THROUGH MONDAY

According to the NHC Advisory 29…The depression is moving toward the west-northwest near 8 mph (13 km/h), and this general motion with a decrease in forward speed is expected through early Monday morning. A slow turn toward the north is expected Monday morning, followed by a motion toward the east-northeast Monday afternoon. A faster motion toward the east-northeast is expected on Tuesday. On the forecast track, Henri is expected to slow down further and possibly stall near the Connecticut-New York border tonight, then move across Massachusetts on Monday afternoon and Monday night and over the Atlantic on Tuesday. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Some additional slow weakening is likely during the next couple of days.

HAZARDS AFFECTING LAND

STORM SURGE: The combination of a dangerous 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…

Flushing, NY to Chatham, MA including Narragansett Bay, Buzzards Bay, Vineyard Sound, and Nantucket Sound…3-5 ft
North shore of Long Island from Flushing to Montauk Point, NY including Long Island Sound…3-5 ft
South shore of Long Island from Mastic Beach to Montauk Point, NY…3-5 ft
Chatham, MA to Sagamore Beach, MA including Cape Cod Bay…2-4 ft
South shore of Long Island from East Rockaway Inlet to Mastic Beach, NY…2-4 ft
Cape May, NJ to East Rockaway Inlet, NY…1-3 ft
Sagamore Beach, MA to Merrimack River including Massachusetts Bay…1-3 ft

The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.

WIND: Tropical storm conditions are expected to continue in the tropical storm warning area into tonight.

RAINFALL: Henri is expected to produce rainfall amounts of 3 to 6 inches over portions of Long Island, New England, southeast New York, New Jersey, and northeast Pennsylvania today into Monday, with isolated maximum totals near 10 inches. Heavy rainfall from Henri may result in considerable flash, urban, and small stream flooding, along with the potential for widespread minor to isolated moderate river flooding.

TORNADOES: A tornado or two may occur today over southern New England.

SURF: Swells generated by Henri should continue to affect Bermuda today. Swells are expected to increase across much of the east coast of the U.S. and Atlantic Canada today and continue into Monday. These swells could cause life-threatening surf and rip current conditions.

 

Disorganized shower activity over the eastern tropical Atlantic is associated with a broad area of low pressure located several hundred miles west-southwest of the Cabo Verde Islands. Little, if any, development is expected to occur during the next couple of days. Some gradual development, however, is possible by the middle to latter part of the week as the system moves northwestward at 10 to 15 mph over the central Atlantic.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 5 days…low…10 percent
