A tornado that crosses a state line is listed once for each state. Ratings are the Enhanced Fujita (EF) scale, assigned after National Weather Service damage surveys. Source: NOAA Storm Prediction Center severe weather database. Past counts do not predict the next tornado.

Be ready in Irvine
Steps from official sources, with each point linked to the page it comes from.
- In a tornado warning, move to an interior room on the lowest floor of a sturdy building, or to your basement or safe room. Avoid windows. (NWS: Tornado watches and warnings)
- A mobile home or tent is not safe. Move to the closest substantial shelter and protect yourself from flying debris. (NWS: During a tornado)
- Being in a vehicle during a tornado is not safe. The best option is to drive to the closest shelter. (NWS: During a tornado)
- Identify and practice going to a safe shelter: a safe room built to FEMA criteria or a storm shelter built to ICC 500 standards. (Ready.gov: Tornadoes)
- The next best protection is a small, interior, windowless room or basement on the lowest level of a sturdy building. (Ready.gov: Tornadoes)
- During a tornado, cover your head and neck with your arms and put furniture or blankets around or on top of you. (Ready.gov: Tornadoes)
- It is never safe to drive or walk into flood waters. Turn around, don't drown. (NWS: Turn Around Don't Drown)
- Never drive around the barriers blocking a flooded road. The road may have collapsed under the water. (NWS: Turn Around Don't Drown)
- Evacuate immediately when water starts to rise, and get to higher ground if you are in a flood-prone or low-lying area. (NWS: During a flood)
- When thunder roars, go indoors. Move from outdoors into a building or a car with a roof. (Ready.gov: Thunderstorms & Lightning)
- Avoid using electronic devices connected to an electrical outlet, and avoid running water. (Ready.gov: Thunderstorms & Lightning)
- Do not drive through flooded roadways. Six inches of fast-moving water can knock you down, and one foot can sweep a vehicle away. (Ready.gov: Thunderstorms & Lightning)
- Do not rely on a fan as your primary cooling device. Fans do not reduce body temperature or prevent heat-related illness. (Ready.gov: Extreme Heat)
- If your home has no air conditioning, find a cooling center, take cool showers or baths, and drink plenty of fluids. (Ready.gov: Extreme Heat)
- Never leave people or pets in a closed car on a warm day. Check on family members, older adults and neighbors. (Ready.gov: Extreme Heat)

- In a winter storm warning, travel can become difficult or impossible. Delay travel until conditions improve. (NWS: Winter watches, warnings and advisories)
- In a blizzard warning, do not travel. If you must, carry a winter survival kit. If you get stranded, stay with your vehicle and wait for help. (NWS: Winter watches, warnings and advisories)
- Heavy ice can bring down trees, utility poles and communication towers, and power and communication outages can last days. (NWS: Ice and Frost)
- Even a thin layer of ice is dangerous to drivers and pedestrians, and bridges and overpasses freeze before other surfaces. (NWS: Ice and Frost)
- Black ice is a thin, patchy layer on roads that is hard to see, most common in early morning, especially when melted snow refreezes overnight. (NWS: Ice and Frost)
