National Weather Service Watches, Warnings, and Advisories

Warning – A warning is issued when a hazardous weather or hydrologic event is occurring, is imminent, or has a very high probability of occurring. A warning is used for conditions posing a threat to life or property.

Advisory – Highlights special weather conditions that are less serious than a warning. They are for events that may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.

Watch – A watch is used when the risk of a hazardous weather or hydrologic event has increased significantly, but its occurrence, location, and/or timing is still uncertain. It is intended to provide enough lead time so that those who need to set their plans in motion can do so.

These definitions are from the National Weather Service Glossary.

Hazard Maps

Note: These maps are general reference and not specific to the current storms. 

California Department of Water Resources’ Best Available Maps (BAM) Website: The floodplains shown delineate areas with potential exposure to flooding for three different storm events: 100-year, 200-year, and 500-year. These flows and resulting flooded area are based on the best available floodplain information and may not identify all areas subject to flooding.

California Department of Water Reroutes’ Levee Flood Protection Zone (LFPZ) Maps: Levee Flood Protection Zone maps estimate the maximum area that may be flooded if a State-Federal levee fails with flows at maximum capacity that may reasonably be conveyed. These maps specifically focus on flood risks associated with State-Federal levees.

FEMA National Flood Hazard Layer: The National Flood Hazard Layer (NFHL) is a geospatial database that contains current effective flood hazard data. FEMA provides the flood hazard data to support the National Flood Insurance Program.

FEMA Flood Map Service Center: The FEMA Flood Map Service Center (MSC) is the official public source for flood hazard information produced in support of the National Flood Insurance Program. Use the MSC to find your official flood map, access a range of other flood hazard products, and take advantage of tools for better understanding flood risk.
