Severe Weather Alert: Allegheny County Under Flash Flood Warning

Allegheny County, PA (October 26, 2023) – A flash flood warning is currently in effect for Allegheny County, Pennsylvania, prompting urgent action from residents. Heavy rainfall has overwhelmed drainage systems, leading to rapidly rising water levels in creeks, streams, and low-lying areas. Authorities are urging residents to take immediate precautions to ensure their safety.

This sudden and severe weather event underscores the importance of being prepared for flash floods, a significant threat in Allegheny County and across the region. Understanding the risks and knowing how to respond can be the difference between safety and serious danger.

What to Do During a Flash Flood Warning:

• Move to higher ground immediately. Do not attempt to drive or walk through floodwaters. Even shallow water can conceal dangerous debris and strong currents.
• Avoid flooded areas. Turn around, don't drown. Floodwaters can rise rapidly and unexpectedly.
• Stay informed. Continuously monitor weather reports and alerts from the National Weather Service (NWS) and local news outlets. You can sign up for emergency alerts through your local government's website.
• Protect your property. Move valuable items to higher levels. Consider sandbagging if time permits.
• Never drive through flooded roads. The depth of water is often deceptive, and even a small amount of water can sweep a vehicle away. Many flood-related deaths occur when people attempt to drive through flooded areas.
• Be aware of potential dangers. Floodwaters can carry contaminants, making them unsafe to contact.

Understanding the Risks of Flash Flooding in Allegheny County:

Intense rainfall events, often associated with thunderstorms, can quickly overwhelm the drainage capacity of the region, resulting in rapid rises in water levels.

Past flash flood events in Allegheny County have demonstrated the devastating impact of these weather phenomena, causing significant property damage, infrastructure disruption, and even loss of life.
