Severe Weather Alert: Allegheny County Braces for Flash Flood Threat Through Wednesday Night

Allegheny County, PA – October 26, 2023 – Residents of Allegheny County are urged to remain vigilant as a severe weather alert remains in effect, warning of a significant flash flood threat through Wednesday night. Torrential rainfall and already saturated ground conditions have prompted the National Weather Service (NWS) to issue a warning, urging residents to take immediate precautions to protect their lives and property.

The NWS predicts heavy rainfall throughout the day, with accumulations potentially exceeding two inches in some areas. This, coupled with the already saturated ground from recent rainfall, creates a perfect storm for flash flooding. Low-lying areas and areas near rivers and streams are particularly at risk. The threat extends across the entire county, impacting communities from Pittsburgh to its surrounding suburbs.

<h3>Understanding the Flash Flood Risk</h3>

Flash floods are characterized by their rapid onset and can occur with little to no warning. Unlike river flooding, which develops more gradually, flash floods can transform a normally dry area into a raging torrent within minutes. This sudden deluge poses a significant danger to life and property. Key risk factors in Allegheny County include:

• Steep Terrain: The hilly landscape of Allegheny County means that water can rush downhill rapidly, overwhelming drainage systems and causing sudden, intense flooding.
• Urban Runoff: Impervious surfaces like roads and parking lots prevent water from absorbing into the ground, leading to increased surface runoff and a greater risk of flooding in urban areas.
• Poor Drainage: Older infrastructure and inadequate drainage systems in some parts of the county exacerbate the flooding risk.

<h3>Safety Precautions and Actions to Take:</h3>

The Allegheny County Emergency Management Agency (ACEMA) strongly advises residents to take the following precautions:

• Monitor Weather Reports: Stay informed about the latest weather updates from the NWS and local news channels.
• Avoid Driving Through Floodwaters: Never attempt to drive through flooded areas. Even a small amount of water can sweep a vehicle away. Turn around, don't drown.
• Move Vehicles to Higher Ground: If you live in a flood-prone area, consider moving your vehicles to higher ground.
• Prepare an Emergency Kit: Have a readily available emergency kit with essentials like water, non-perishable food, flashlights, and a first-aid kit.
• Know Your Evacuation Route: Familiarize yourself with your evacuation route in case authorities issue an evacuation order.
• Sign up for Emergency Alerts: Register for emergency alerts through your local municipality or county to receive timely warnings.
