On this track the center of Henri will likely make landfall close to the Connecticut Rhode Island border early this afternoon, and then track farther north into southern New England through Monday while weakening. The main threats from Henri continue to be heavy rain capable of producing flash flooding and river flooding, tropical storm force winds, and potentially life-threatening storm surge. There will also be associated marine and coastal hazards including very rough seas, high surf, dangerous rip currents, and beach erosion. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Potential impacts from flooding rain are still unfolding across Southeast New York, Northeast New Jersey, and Southern Connecticut. Remain well guarded against life-threatening flood waters having additional extensive impacts. If realized, these impacts include: - Major rainfall flooding may prompt 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 downhill and increase susceptibility to rockslides. - 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. * WIND: Potential impacts from the main wind event are now unfolding, mainly across the forks of Long Island and across southeast Connecticut. Remain well sheltered from strong winds having additional significant impacts. If realized, these impacts include: - Some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds. A few buildings experiencing window, door, and garage door failures. Mobile homes damaged, especially if unanchored. Unsecured lightweight objects become dangerous projectiles. - Several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Several fences and roadway signs blown over. - Some roads impassable from large debris, and more within heavily wooded places. - Scattered power and communications outages, more prevalent in areas with above ground lines. * SURGE: Potential impacts from the main surge event are now unfolding across the shorelines of Long Island Sound, Peconic and Gardiners Bays, and Moriches and Shinnecock Bays. Remain well away from life-threatening surge having possible significant impacts. If realized, these impacts 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. Potential impacts from the main surge event are also now unfolding across the Great South Bay, Jamaica Bay, and New York Harbor. Remain well away from locally hazardous surge having possible limited impacts. * OTHER COASTAL HAZARDS: High surf, dangerous rip currents, beach flooding, dune erosion, and localized overwashes are all possible at the ocean beaches, especially across eastern Suffolk County. * TORNADOES: Potential impacts from an isolated tornado or two are still unfolding across southeast Connecticut in heavy rain bands. If realized, impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans. - 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. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: 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. If evacuating, leave with a destination in mind and allow extra time to get there. Take your emergency supplies kit. Gas up your vehicle ahead of time. Let others know where you are going prior to departure. Secure loose items and pets in the car. Avoid distracted driving and follow designated evacuation routes. Seek traffic information on roadway signs, on the radio, and from official sources. Do not enter evacuated areas until officials have given the all clear to return. * OTHER PREPAREDNESS INFORMATION: Now is the time to stay inside and away from windows. Listen for updates and be ready in case you lose electrical power. Keep a battery powered radio, charged cell phone and flashlight handy. During the peak of the storm be ready to move quickly. Keep your shoes on and rain gear handy. Boots and athletic shoes offer the best foot protection if you become unexpectedly exposed to the weather. Keep your cell phone charged and in power saving mode. If you lose power, use it sparingly and mainly for personal emergencies and checkins. If you are prone to flooding or in an area under a storm surge watch or warning, be prepared for the possibility of a quick and dramatic rise in water levels. If a tornado warning is issued for your area, quickly move to the safest place within your shelter. Protect your head and body. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see http://ready.gov - For information on creating an emergency plan see http://getagameplan.org - For additional disaster preparedness information see http://redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in New York NY around 5 PM EDT, or sooner if conditions warrant. $$
