Regardless of the exact track of Idalia, significant impacts are expected for eastern North Carolina. Heavy rain bands will continue to bring widespread additional rainfall amounts of 2 to 4 inches, with isolated additional amounts up to 8 inches possible, bringing the threat of localized flash flooding especially in low-lying, urban, and poor drainage areas. Dangerous storm surge inundation of 2-4 feet above ground is possible along the Neuse and Pamlico Rivers and associated tributaries, as well as Core and southern Pamlico Sounds. Winds approaching tropical storm force could lead to some downed trees and isolated power outages, especially along and east of Highway 17. Tornadoes may result in areas of locally enhanced damage, particularly for the Outer Banks. Dangerous marine conditions are expected for all offshore waters and the Pamlico Sound, with strong winds and dangerous seas building to create treacherous conditions for mariners. Localized ocean overwash is expected along the coast due to high surf. Stronger and more frequent rip currents will also exist along area beaches. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Potential impacts from the flooding rain are still unfolding across all of eastern North Carolina. Remain well guarded against life-threatening flood waters having additional extensive impacts. If realized, these impacts include: - Major rainfall flooding may prompt many evacuations and rescues. - Rivers and tributaries 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. - 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. Potential impacts from the flooding rain are still unfolding across all of eastern North Carolina. Remain well guarded against dangerous flood waters having significant impacts. * SURGE: Protect against life-threatening surge having possible significant impacts across the Neuse and Pamlico River and adjacent tributaries as well as the southern Pamlico and Core Sounds. 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. - Major beach erosion with heavy surf breaching dunes. Strong and numerous 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 the Albemarle Sound, Outer Banks, and Crystal Coast. * WIND: Protect against dangerous wind having possible significant impacts across the immediate Crystal Coast. 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. Also, protect against hazardous wind having possible limited impacts across the remainder of eastern North Carolina, particularly east of Highway 17. * TORNADOES: Potential impacts from tornadoes are still unfolding across the Outer Banks. Remain well braced against a tornado event possible limited impacts. If realized, these 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 Eastern North Carolina, little to no impact is anticipated. * OTHER COASTAL HAZARDS: Dangerous marine conditions are expected across all the waters, with strong winds and seas building to create treacherous conditions for mariners. Life-threatening surf conditions with stronger and more frequent rip currents and strong shore break will also exist along area beaches. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * 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 check-ins. Do not be a thrill seeker or risk your life for senseless photos or videos. 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 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 Newport/Morehead City NC around 12 PM EDT, or sooner if conditions warrant. $$
