(KTXL) — As a third atmospheric river in two weeks hits California and the state expects a few more storms to arrive in the coming days, state officials declared a state of emergency due to possible widespread flooding.
Local governments, such as the City of Sacramento, advised residents to stay safe during the storms and emphasized the region’s vulnerability to flooding from local waterways.
The City of Sacramento has a map showing areas in the city that depend on levees, meaning areas that avoid flooding only as long as the levees hold.
Levees around the two major rivers, the Sacramento and the American, are rated to handle what is known as a 200-year storm, meaning that any year has a 0.5% chance of seeing a storm of that magnitude.
The atmospheric rivers that are hitting the state are not expected to reach such a strong level, but can still cause flooding.
