    By: Megan McClellan


    Quick Facts

    • Flash Flood Watches have been posted for much of Green Country from Friday evening through Sunday morning
    • Green Country will see lots of rain, some localized areas could see more than 7 inches of rain
    • Remember when you see water on the roadway -- Turn Around, Don't Drown
    • 12 inches of water can float a car or small SUV
    • 6 inches of water can knock an adult over


    With another chance of strong to severe storms moving in to end the work week, there is also the chance that Green Country could be dealing with flooding conditions again similar to last week.

    The FOX23 Severe Weather Team began telling you about severe storm chances for this weekend early in the week and warning viewers about the flooding potential. Multiple rounds of rain will be moving through starting Friday and continuing through Saturday.

    Different Types of Flood  Alerts

    The National Weather Service not only tracks the heavy rain, but it also forecasts for several rivers around Green Country. There are several different types of flooding alerts that are issued by the National Weather Service:

    • Flood Advisory
    • Flood Watch
    • Flood Warning
    • Flash Flood Warning
    • River Flooding


    A Flood Advisory is issued when flooding is expected but is not going to be bad enough to issue a warning. The flooding can cause an inconvenience and could lead to situations that may threaten life and/or property.

    A Flood Watch will be issued when conditions are favorable for flooding (similar to when a thunderstorm watch or tornado watch are issued -- conditions are favorable).

    Flood Warnings are issued when flooding is either happening or imminent.

    Flash Flood Warnings are issued when a flash flood (or floods that happen within 6 hours of the cause) is happening. Flash floods can take a few hours to develop or can develop within minutes.

    River flooding happens when levels rise and overflow their banks. There are three categories for river flooding based on the water height and impacts:

    • Minor - areas right around the river/stream may see some problems
    • Moderate - levels rise high enough to impact homes/businesses near the river may need to evacuate; roads may be impacted
    • Major - extensive flooding is expected; major traffic routes may be flooded, numerous evacuations may be required


    Before a Flood

    In the days or hours leading up to an event that could cause some flooding, be sure you are aware of some flooding areas that could impact you, whether it is near your home or on your daily commute. Areas that are known for flooding in Tulsa can be found in the map below:


    During a Flood

    During a flood or potential flooding event, water levels can change very quickly along with the rate the water is flowing. Since things can change quickly, be sure that you are staying aware and alert but monitoring the conditions. 

    It is also key to follow any evacuation orders and avoid flood waters. When a flood is happening, the water can be deeper than it seems on roadways and even in the creeks/rivers.

    Some facts that can help you think about the flooding water:

    • 6 inches of flowing water can knock over an adult
    • 12 inches of water can float a car or small SUV
    • 2 feet of water can carry away most vehicles

    If you are unsure how the deep the water is, it is best to remember "Turn Around, Don't Drown". That includes driving through or walking through any water.

    After a Flood

    Once the flood waters recede and the "all-clear" is given, there can be more problems left behind. Some of the problems can include power outages, debris and toxins/chemicals carried by the water.


    The FOX23 Weather App is a great way to stay aware ahead of a flooding event and during flooding events. You can get alerts sent directly to your phone for your current location or for any location of your choosing. Details on the FOX23 Weather App can be found here: FOX23 Weather App details
