Our Current Situation
All the rain that we have had over the last couple of days has added up and we are starting to see urban flash flooding and water rescues.
Unfortunately, we will be seeing more rain through Thursday afternoon as this low-pressure system swings through the area.
Right now we are in the thick of it and on the eastern side of the low pressure. This southerly flow is combining with the plume of tropical moisture from Hurricane Delta and creating high rainfall rates.
Being under a drought-stricken pattern has not helped us, and has caused a lot of the soil to dry out. Therefore the ground is not doing a very good job of absorbing rainfall. This leads to flash flooding very quickly in those low lying areas, especially near streams and rivers.
An Areal Flood Warning means that local creeks and streams are becoming overrun and causing low lying areas to flood. We are also seeing some urban or city flooding as well across Northwest Arkansas and the River Valley.
A Flood Warning is issued when parts of a river are expected to crest in the coming days above flood stage. This could cause some roads to become impassable and low lying areas to flood.
How much have we seen?
Alma had received at least 5 inches of rain. Most of the River Valley has seen at least 2-3 inches of rainfall over the last 3 days. All of this rain has already caused some highways across the River Valley to close!
Here are the closures we know about. According to IDrive Arkansas Highway 282 in Crawford County and Highway 255 in Sebastian County are both closed due to impassable high water!
How much more rain is expected?
We are expecting at LEAST one more inch of rainfall before all is said and done! The rain will start to lighten up as we head into the evening, and into the morning Thursday as we get on the backside of the departing low pressure system.
Turn Around Don’t Drown!
If you come across flooded roadways make sure to TURN AROUND, DON’T DROWN! Your life is NOT worth the risk to save extra time. Find another route around the flooded area.
If you can safely take pictures of the flooding across the region please send them to our weather team at firstname.lastname@example.org or on our NWA Weather Authority App.
