Air Quality Alert issued April 14 at 5:26PM EDT by NWS Wilmington NC

Non-Weather Emergency Message. Not sent to IPAWS.

Effective: Tue April 14, 2026, 5:26 PM
Expires: Wed April 15, 2026, 1:00 PM

The South Carolina Department of Environmental Services (SCDES) has issued an Air Quality Alert for fine particulates for Horry County through Wednesday, April 15th. An Air Quality Alert means that the fine particulate concentrations within the specified areas may approach or exceed unhealthy standards due to a large wildfire in Marion County and continued smoke in the Conway area. High pressure over the Southeast U.S. will cotninue to dominate the region today and tomorrow, minimizing smoke dispersion from the ongoing wildfire in Marion County. Stable conditions and little wind will enhance the noticeability of smoke, especially in the overnight and morning hours. Stagnant conditions are expected to pin smoke to ground level until midday Wednesday. SCDES recommends that individuals with respiratory health issues limit time spent outdoors and/or move all activities indoors to avoid the smoke or fine particulates. Keep windows and doors closed. Run an air conditioner if you have one but keep the fresh air intake closed and the filter clean to prevent outdoor smoke and fine particulates from getting inside. Please note that locations closest to the wildfire activity are more likely to experience smoke at any given time. For more information about fine particulates, please visit: https://fire.airnow.gov For more information about wildfires/prescribed burns, please visit: https://www.scfc.gov If your see or smell smoke, take the necessary precautions to protect your health.

Effective: Wed April 15, 2026, 6:06 AM
Expires: Wed April 15, 2026, 7:00 PM

The combination of dry fuels, low relative humidity, and gusty winds will lead to increased fire danger today. Winds will be south to southwest 10 to 15 mph with gusts to 20 mph.

Please refer to your local burn permitting authorities on whether you can burn. If you do, you are advised to use extreme caution.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
