SALT LAKE CITY (ABC 4) – The National Weather Service currently has two Flash Flood Warnings in effect for southern Utah, both straddling the line of Kane and Washington Counties. The first is set to expire soon but can still pose threats into the evening. It is centered over Zion Lodge and extends as far south as Rockville. As stated, it is set to expire soon, but the area should be considered dangerous for now.
The second Flash Flood Warning is at the southern border of the state near Kanab and extends westward into Washington County and will remain in effect until 5:45 PM MDT. Radar is indicating thunderstorms producing heavy rain in an area where we’ve already seen rainfall and flash flooding is either ongoing or expected to begin shortly. The area most affected by this warning is in the Coral Pink Sand Dunes. If you know people who were planning on being in that area, please alert them.
Flash Floods can cause life-threatening conditions around creeks and streams, urban areas, highways, streets, and underpasses.
We are also following an Areal Flood Advisory around Cedar City that should be in place until 5:45 PM MDT. Areal Flood Advisories are put in place when it is expected that low-lying and poor drainage areas are seeing enough rain that they might begin to flood. There are strong rains expected to continue in that area and all people in that area should be advised to make sure that they are in higher elevated areas.
We will be following all the weather conditions as they happen both online and on-air.
