For more recent tornadoes, clicking deeper provides more details, damage estimates and whether someone was injured or killed in the storm. This interactive map, which contains data from January 1950, pinpoints where a cyclone touched down and traces its path of destruction. A history of twisters: Tornadoes in Florida since 1950s Rolling Storm Damage ReportsĪs storms strike, this interactive map is your guide to impacts and damage reports coming into National Weather Service stations nationwide. Track all current severe weather warnings, watches and advisories for Redding, California and other areas in the United States on the interactive weather alerts page. Weather Alerts: Warnings, Watches and Advisories It will automatically update every 15 minutes. For more detail, please see Cal Fire’s official county maps for both state and local responsibility areas.As severe weather or blizzards threaten, this database scrapes power outage information from more than 1,000 companies nationwide. Note: KQED has simplified these maps for online display. After that, Cal Fire will work with local governments to develop new maps for those areas, too. The agency expects to release official maps next summer for “state responsibility areas” - the parts of California areas that it’s responsible for protecting. “You don’t want to zone that house based on what’s there, but what could potentially be there,” Sapsis says.Ĭal Fire hopes to start testing its new draft maps this winter. In urban areas, fires can move quickly through dense neighborhoods where homes are tightly spaced. The new maps are meant to show “where fires could go,” not where they could start, Sapsis says.įor instance, development patterns can change how fire spreads. But the risk, or how much damage a fire can do, depends on the built environment. Those kinds of weather conditions are tricky to map, Sapsis says, because you want to take into account those very destructive types of fires, but also need to consider a longer, 50-year period.įire “hazard” is a measure of how a fire will behave, based on the physical conditions. “We’re just now getting the capacity to estimate at a realistic scale what these areas, footprints, if you will, of these dry windy events are … and what the magnitudes of these events are,” Sapsis says. Sapsis says that fire modeling technology is improving all the time, and that the new models Cal Fire is testing are taking into account dry, windy weather. Original 2019 story continues below New Maps to Assess Weather and Development (Cal Fire was expected to release new draft maps to test in winter 2019/2020 that took new risk factors into account. We do the best we can based on the tools we have,” he says.Īnd, as recent fires have tragically demonstrated, living outside a higher-risk zone doesn’t mean that you’re safe.Įxtreme winds drove much of the damage in Paradise during last the November 2018 Camp Fire and in the North Bay during the October 2017 fire siege, and current fire maps don’t take that factor into account. “Estimating a burn probability is an estimate. Sapsis says it’s important to remember that the Cal Fire-defined risk zones are showing only a probability. “How likely is the fire? And what is the nature of the fire?” “The model is basically trying to describe areas and their likelihood for a structure to ignite,” Dave Sapsis, a Cal Fire researcher who specializes in mapping and research models, told KQED in 2019.
