Understanding the Thunderstorm Watch

It’s crucial to understand the difference between a thunderstorm watch and a warning. A thunderstorm watch means that conditions are favorable for severe thunderstorms to develop in and around South-Central PA. This isn't a guarantee of severe weather, but it's a strong indication that the potential exists. The National Weather Service issues watches based on various factors, including atmospheric instability (the air's tendency to rise and create thunderstorms), high moisture content (fueling thunderstorm development), and wind shear (changes in wind speed and direction with altitude) within the South-Central PA region.

• A watch means: Conditions are favorable for severe thunderstorms to develop. Be prepared to act quickly if conditions worsen.
• A warning means: Severe thunderstorms are imminent or already occurring in your area. Take immediate action to protect yourself and your property.
• Stay informed: Remain updated through reliable sources like NOAA Weather Radio, your local news channels, and reputable weather apps.

Potential Hazards Associated with the Severe Thunderstorm Watch

The severe thunderstorm watch for South-Central PA carries the potential for several significant hazards:

High Winds

Severe thunderstorms can produce damaging winds exceeding 58 mph. These high winds pose a serious threat, capable of causing:

• Downed power lines: Stay away from downed power lines – assume they are live and extremely dangerous.
• Damaged trees: Falling trees can cause significant property damage and injury. Trim overhanging branches before a storm to minimize the risk.
• Potential power outages: Prepare for potential power outages by having flashlights, batteries, and a fully charged cell phone.

Flash Flooding

Heavy rainfall associated with severe thunderstorms can lead to flash flooding, especially in low-lying areas, near rivers, streams, and urban areas with poor drainage.

• Avoid floodwaters: Never drive or walk through floodwaters; even a few inches of water can sweep you off your feet.
• Know your evacuation routes: If you live in a flood-prone area, familiarize yourself with your evacuation route and have a plan in place.
• Monitor water levels: Pay close attention to water levels and heed all flood warnings issued by authorities.

Hail

Large hail can accompany severe thunderstorms, causing significant damage to property and posing a risk of injury. Hailstones can range in size from small pebbles to golf balls or even larger.

• Seek shelter indoors: Move to a sturdy interior room away from windows during a hailstorm.
• Protect vehicles: Park vehicles in garages or under covered areas to protect them from hail damage.

Safety Precautions and Emergency Preparedness

Proactive preparation is crucial for mitigating the risks associated with severe weather.

• Develop a family emergency plan: Establish a communication plan and determine meeting locations in case of separation during the storm. Consider evacuation routes and shelter options.
• Prepare an emergency kit: Stock an emergency kit with essentials such as water (one gallon per person per day), flashlights, extra batteries, a first-aid kit, non-perishable food, medications, and important documents.
• Review safety measures: Know what to do during a severe thunderstorm at home, in your car, and while outdoors.
• Stay informed: Continuously monitor official weather updates from the National Weather Service and local news for changes in the severe weather alert.
