What Is a Tornado Warning?
A tornado warning is an urgent alert issued by the National Weather Service (NWS) when a tornado has been sighted or when weather radar indicates that a tornado is highly likely to form. Unlike a tornado watch, which signals that conditions are favorable for tornado development, a warning indicates imminent danger. The time to act is now.

Why Tornadoes Are Rare in San Diego
San Diego's geographical location and Mediterranean climate make it an unlikely place for tornadoes. Tornado formation usually requires specific atmospheric conditions, such as significant temperature contrasts, moisture, and wind shear, which are more prevalent in the central and southeastern United States. However, certain anomalies in weather patterns can create the rare conditions necessary for tornado development in Southern California.
...
Recent Tornado Warnings in San Diego
Although tornado warnings are rare in San Diego, there have been instances in recent years where such warnings have been issued. For example, in [INSERT YEAR], the National Weather Service issued a tornado warning for parts of San Diego County following the detection of a severe weather system. While the tornado did not materialize, the event underscored the importance of remaining vigilant.
...
The Science Behind Tornado Formation
Tornadoes form when warm, moist air meets cold, dry air, creating instability in the atmosphere. Add wind shear—changes in wind speed and direction with altitude—and you have the recipe for a tornado. The rising warm air tilts the wind shear into a vertical position, creating a rotating column of air, which can sometimes develop into a tornado if conditions persist.

How to Stay Alert During a Tornado Warning
Staying informed is your first line of defense during a tornado warning. Have a reliable source of weather updates, such as a NOAA weather radio, smartphone apps, or alerts from local news stations. Make sure these devices are set to notify you immediately when a warning is issued.

What to Do During a Tornado Warning
When a tornado warning is issued, take immediate action. If you are indoors, head to your designated safe room or the lowest level of your building. Stay away from windows, doors, and outside walls. If you are outdoors, seek shelter in a sturdy building or lie flat in a low-lying area, covering your head with your hands.

Post-Tornado Safety Measures
Once the tornado threat has passed, prioritize safety. Avoid downed power lines, damaged buildings, and floodwaters. Check on neighbors and family members, and report any injuries or hazards to local authorities. Document property damage for insurance purposes and take photographs as evidence.
...
How Climate Change Affects Tornado Patterns
Climate change has been linked to shifts in tornado patterns, with some studies suggesting increased frequency and intensity in atypical regions like California. Warmer ocean temperatures and altered jet stream patterns may contribute to these anomalies, making it even more critical to stay prepared.
...
Role of Local Government and Emergency Services
Local government and emergency services play a vital role during tornado warnings. From issuing timely alerts to coordinating evacuation and relief efforts, their actions can save lives. In San Diego, agencies like the Office of Emergency Services (OES) work closely with the NWS to provide accurate and timely information to residents.
