Understanding Severe Thunderstorm Watches and Warnings

The terms "watch" and "warning" are often confused, but understanding their differences is vital for your safety. A severe thunderstorm watch means conditions are favorable for severe thunderstorms to develop. It's a time to prepare. A severe thunderstorm warning, however, signifies that severe thunderstorms are happening now in your area. Immediate action is required.

Severe thunderstorms are characterized by at least one of the following:

• High winds: Gusts exceeding 58 mph (93 km/h).
• Large hail: Hailstones larger than 1 inch (2.5 cm) in diameter.
• Heavy rain: Leading to flash flooding, especially in low-lying areas and canyons.
• Frequent lightning: Posing a significant risk of fire and electrocution.

Historically, areas like the East Bay hills, Santa Cruz Mountains, and North Bay valleys have experienced more frequent and intense severe thunderstorm activity.

Action Steps:

During a Watch:

• Monitor weather reports closely.
• Review your emergency plan.
• Secure outdoor furniture and belongings.
• Charge electronic devices.

During a Warning:

• Seek immediate shelter indoors.
• Stay away from windows and doors.
• Avoid using electronic devices.

Safety Precautions During a Severe Thunderstorm

Protecting Yourself Indoors

When a severe thunderstorm warning is issued, immediately move to a safe interior location. Here's what to do:

• Stay away from windows and doors: These are the most vulnerable points of entry for flying debris and strong winds.
• Unplug electronic devices: Lightning can travel through electrical systems, damaging appliances and posing a fire hazard.
• Avoid using landline phones: Landlines are more susceptible to lightning strikes than cordless phones.
• Find a safe interior room: An interior room on the lowest level of your home, away from exterior walls and windows, is ideal.
• Power Outage Procedures:
  • Have flashlights and battery-powered lanterns readily available.
  • Avoid using candles due to fire hazards.
  • Never use a generator indoors.

Staying Safe Outdoors

If you're caught outdoors during a severe thunderstorm, your priority is to get to safety immediately.

• Seek immediate shelter indoors: This is the safest option.
• Never stay under a tree: Trees are excellent conductors of electricity and are frequently struck by lightning.
• Avoid open fields and elevated areas: These areas are more susceptible to lightning strikes.
• If caught in an open area: Crouch low to the ground, minimizing your contact with the earth. Avoid lying flat.
• Avoid contact with metal objects: Metal is a conductor of electricity.
• Driving During a Storm:
  • Pull over to a safe location, away from trees and power lines.
  • Turn on your hazard lights.
  • Wait for the storm to pass before resuming your journey.

Preparing Your Home for Severe Thunderstorms

Proactive preparation is key to minimizing risks during severe weather events.

• Create a family emergency plan: Include meeting points, evacuation routes, and contact information.
• Develop a communication plan: Designate an out-of-area contact person for family members to check in with.
• Secure outdoor furniture and loose objects: Strong winds can easily toss lightweight items, causing damage.
• Trim trees and shrubs: Overgrown vegetation can increase the risk of damage from falling branches.
• Assemble an emergency kit: Include flashlights, extra batteries, bottled water, a first-aid kit, non-perishable food, blankets, and a battery-powered radio. For Bay Area-specific needs, consider adding sandbags (for potential flooding), extra medications, and a waterproof container for important documents.
