It is forecast to make landfall as a major hurricane in the Big Bend region of Florida around 8 this morning. After making landfall, Idalia is expected to track over southeast Georgia and just inland of the southeast South Carolina coastline Wednesday evening through early Thursday morning. Local impacts from Idalia begin this morning as heavy rainfall begins to overspread southeast Georgia and southern South Carolina.

Tropical Storm force winds, along with isolated tornadoes, will be possible across the eastern Midlands by Wednesday afternoon and into early Thursday morning. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Prepare for life-threatening rainfall flooding having possible extensive impacts across the eastern Midlands. Potential 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, arroyos, and ditches may become dangerous rivers. In mountain areas, destructive runoff may run quickly down valleys while increasing susceptibility to rockslides and mudslides. 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. Prepare for dangerous rainfall flooding having possible significant impacts across the western Midlands and CSRA. * WIND: Protect against dangerous wind having possible significant impacts across the central South Carolina Midlands and CSRA of central Georgia. 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. * TORNADOES: Prepare for a dangerous tornado event having possible significant impacts across the eastern Midlands of SC. Potential impacts include: - The occurrence of scattered tornadoes can hinder the execution of emergency plans during tropical events. - Several places may experience tornado damage with a few spots of considerable damage, power loss, and communications failures. - Locations could realize roofs torn off frame houses, mobile homes demolished, boxcars overturned, large trees snapped or uprooted, vehicles tumbled, and small boats tossed about. Dangerous projectiles can add to the toll. Prepare for a tornado event having possible limited impacts across the eastern Midlands of SC. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: No evacuations are currently ongoing across the Midlands or CSRA. * OTHER PREPAREDNESS INFORMATION: |Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding. 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. 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! Closely monitor 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. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information from the state of South Carolina see scemd.org - For information from the state of Georgia see gema.ga.gov NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Columbia SC around 11 AM EDT, or sooner if conditions warrant. $$
