**HURRICANE CONDITIONS EXPECTED ACROSS PORTIONS OF EASTERN LONG ISLAND AND SOUTHERN CONNECTICUT SUNDAY* NEW INFORMATION —————
CHANGES TO WATCHES AND WARNINGS: – None
CURRENT WATCHES AND WARNINGS: – A Hurricane Warning and Storm Surge Watch are in effect for Southwest Suffolk – A Tropical Storm Warning is in effect for Eastern Bergen, Eastern Essex, Eastern Union, Hudson, Kings (Brooklyn), New York (Manhattan), Northern Fairfield, Northern Westchester, Richmond (Staten Island), and Southern Queens – A Tropical Storm Warning and Storm Surge Watch are in effect for Southern Nassau – A Hurricane Warning is in effect for Northern Middlesex, Northern New Haven, and Northern New London – A Storm Surge Warning and Hurricane Warning are in effect for Northeast Suffolk, Northwest Suffolk, Southeast Suffolk, Southern Middlesex, Southern New Haven, and Southern New London – A Storm Surge Warning and Tropical Storm Warning are in effect for Bronx, Northern Nassau, Northern Queens, Southern Fairfield, and Southern Westchester
STORM INFORMATION: – About 220 miles southeast of New York City NY or about 180 miles south-southeast of Montauk Point NY – 38.6N 71.0W – Storm Intensity 75 mph – Movement North or 355 degrees at 21 mph
SITUATION OVERVIEW ——————
Henri remains a Category 1 hurricane and is currently 180 miles south southeast of Montauk Point. Henri will likely make landfall near hurricane strength between the east end of Long Island and Narragansett Bay Sunday, and then track into southern New England late Sunday into Monday as it weakens.
The main threats from Henri continue to be potentially life- threatening storm surge, heavy rain capable of producing flash flooding, tropical storm or hurricane force winds along the south shore of Long Island and across southern Connecticut. There will also be associated marine and coastal hazards, including very rough seas and dangerous rip currents.
Severe beach erosion is possible for coastal areas of Long Island Sound and portions of Suffolk County, including the Twin Forks region.
A widespread rainfall of 3 to 6 inches is forecast in the path of Henri with localized higher amounts possible late tonight through Monday. The highest amounts are forecast to be across Long Island and much of southern Connecticut and may occur along and west of the center of Henri. This will present a likelihood for areas of flash flooding.
Dangerous marine conditions are likely on the ocean waters south of Long Island, as well as on Long Island Sound, and the south shore and eastern bays of Long Island. Dangerous rip currents and high surf are expected along the ocean beaches of Long Island.
POTENTIAL IMPACTS —————–
WIND: Protect against life-threatening wind having possible extensive impacts across eastern Long Island and southern Connecticut. Potential impacts in this area include: – Considerable roof damage to sturdy buildings, with some having window, door, and garage door failures leading to structural damage. Mobile homes severely damaged, with some destroyed. Damage accentuated by airborne projectiles. Locations may be uninhabitable for weeks. – Many large trees snapped or uprooted along with fences and roadway signs blown over. – Some roads impassable from large debris, and more within urban or heavily wooded places. Several bridges, causeways, and access routes impassable. – Large areas with power and communications outages.
Also, protect against dangerous wind having possible limited to significant impacts across New York City metro area, portions of the Lower Hudson Valley, and portions of northeastern New Jersey.
SURGE: Protect against life-threatening surge having possible significant impacts across all coastal areas of Long Island Sound, and much of the Great South Bay and southeast coast of Long Island. Potential impacts in this area include: – Areas of inundation with storm surge flooding accentuated by waves. Damage to several buildings, mainly near the coast. – Sections of near shore escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. Flood control systems and barriers may become stressed. – Major beach erosion with heavy surf breaching dunes. Very dangerous surf and rip currents. – Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages.
Also, protect against locally hazardous surge having possible limited impacts across Jamaica Bay, and New York Harbor.
Elsewhere across Southeast New York, Northeast New Jersey, and Southern Connecticut, little to no impact is anticipated.
FLOODING RAIN: Protect against life-threatening rainfall flooding having possible extensive impacts across Southeast New York, Northeast New Jersey, and Southern Connecticut. Potential impacts include: – Major rainfall flooding may prompt many evacuations and rescues. – Rivers and streams may rapidly overflow their banks in multiple places. Small streams, creeks, canals, and ditches may become dangerous rivers. Flood control systems and barriers may become stressed. – In hilly terrain, destructive runoff may run quickly down valleys, and increase susceptibility to rockslides and mudslides. – Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out.
TORNADOES: Protect against a tornado event having possible limited impacts across eastern Long Island and southeast Connecticut. Potential impacts include: – The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. – A few places may experience tornado damage, along with power and communications disruptions. – Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings.
Elsewhere across Southeast New York, Northeast New Jersey, and Southern Connecticut, little to no impact is anticipated.
PRECAUTIONARY/PREPAREDNESS ACTIONS ———————————-
EVACUATIONS: Listen to local official for recommended preparedness actions, including possible evacuation. If ordered to evacuate, do so immediately.
For those not under evacuation orders, assess the risk from wind, falling trees, and flooding at your location. If you decide to move, relocate to a safer location nearby. If you do not relocate, help keep roadways open for those under evacuation orders.
OTHER PREPAREDNESS INFORMATION: Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Make sure you are in a safe location before the onset of strong winds or possible flooding.
If you are relocating to safe shelter, leave as early as possible. Allow extra time to reach your destination. Many roads and bridges may be closed once strong winds arrive. Check the latest weather forecast before departing and drive with caution.
Failure to adequately shelter may result in serious injury or loss of life. Always heed the advice of local officials and comply with any orders that are issued. Remember that during the storm 9 1 1 Emergency Services may not be able to immediately respond if conditions are unsafe. This should be a big factor in your decision making.
Keep cell phones well charged. Cell phone chargers for automobiles can be helpful, but be aware of your risk for deadly carbon monoxide poisoning if your car is left idling in a garage or other poorly ventilated area.
Storm surge is the leading killer associated with tropical storms and hurricanes! Make sure you are in a safe area away from the surge zone. Even if you are not in a surge prone area, you could find yourself cut off by flood waters during and after the storm. Heed evacuation orders issued by local authorities.
Rapidly rising flood waters are deadly. If you are in a flood prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, Turn Around Don’t Drown!
If in a place that is vulnerable to high winds, such as near large trees, a mobile home, upper floors of a high rise building, or on a boat, consider moving to a safer shelter before the onset of strong winds or flooding.
Closely monitor http://weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings.
