Henri is expected to strengthen to hurricane force before making landfall over Long Island on Sunday afternoon. The main threat with this system is for tropical storm force winds in northeast New Jersey. Locally heavy rain may lead to localized flash flooding in northeast New Jersey. With a full moon this weekend, minor coastal flooding is possible, but if Henri takes a more western track closer to New Jersey, more widespread and significant coastal flooding will be possible for New Jersey. Dangerous marine conditions will develop over the northern Atlantic Waters with strong winds, rough seas, and dangerous rip currents. Seas will build to six to ten feet. Dangerous rip currents will likely occur along the ocean beaches of New Jersey. POTENTIAL IMPACTS ----------------- * WIND: Prepare for dangerous wind having possible significant impacts across portions of northeast New Jersey. Potential impacts in this area 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 urban or heavily wooded places. A few bridges, causeways, and access routes impassable. - Scattered power and communications outages, but more prevalent in areas with above ground lines. * FLOODING RAIN: Prepare for dangerous rainfall flooding having possible significant impacts across portions of northeast New Jersey. Potential impacts include: - Moderate rainfall flooding may prompt several evacuations and rescues. - Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, canals, arroyos, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures. * SURGE: Little to no impacts are anticipated at this time across NEW JERSEY. 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 check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business. When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes extend well away from the center of the storm. Always heed the advice of local officials and comply with orders that are issued. Do not needlessly jeopardize your life or the lives of others. Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Mount Holly NJ around 12 AM EDT, or sooner if conditions warrant. $$ $$
