Expected Rainfall and Timing

The Pennsylvania flash flood warning is issued due to the anticipated volume and intensity of rainfall. The following details provide a better understanding of what to expect:

• Rainfall Totals: Rainfall totals of 3-6 inches are expected across the affected regions, with localized amounts possibly exceeding 8 inches in some areas. This level of rainfall in a short period significantly increases the risk of flash flooding.

• Timeframe: The heaviest rainfall is expected to occur from Tuesday evening through Wednesday morning. However, periods of heavy rain are likely to continue into Thursday, maintaining the elevated risk of flash flooding throughout this period.

• Thunderstorms: The heavy rainfall will be accompanied by thunderstorms, potentially bringing strong winds and lightning alongside the torrential rain. This increases the danger and requires heightened awareness.

• Localized Heavier Downpours: Be aware that localized areas could experience even higher rainfall amounts than the predicted averages. Small creeks and streams can quickly swell and become dangerous even with relatively small increases in rainfall.

Safety Precautions and Emergency Preparedness

Taking proactive safety measures is crucial during a Pennsylvania flash flood warning. Your safety and the safety of your family should be your top priority.

• Turn Around, Don't Drown: Never attempt to drive through flooded areas. The depth of the water may be deceiving, and even a few inches of fast-moving water can sweep away a vehicle.

• Stay Away from Waterways: Avoid all contact with rivers, streams, and other bodies of water during and after the heavy rainfall. These waterways can rise rapidly and unexpectedly.

• Monitor Weather Reports: Stay updated on the situation by regularly checking NOAA weather reports, local news, and official government advisories for the latest information on the Pennsylvania flash flood.

• Prepare an Emergency Kit: Assemble an emergency kit containing essential supplies such as bottled water, non-perishable food, a first-aid kit, flashlights, batteries, and a portable radio.

• Know Your Evacuation Routes: If you live in a flood-prone area, familiarize yourself with your evacuation routes and have a plan in place.

• Sign Up for Emergency Alerts: Register for emergency alerts through your local government to receive timely warnings and instructions during severe weather events.

What to do if you experience flooding

If flooding occurs near you, immediate action is vital.

• Move to Higher Ground: If you are in a flooded area, move to higher ground immediately. Do not wait for official instructions; your safety is paramount.

• Contact Emergency Services: If you need assistance, contact your local emergency services immediately.

• Secure Valuable Possessions: If possible, move valuable possessions to a safe, dry location before they are damaged by floodwater.

• Avoid Floodwater Contact: Floodwater can contain dangerous contaminants, so avoid all contact with it. Wait for authorities to declare the water safe before entering flood-affected areas.
