San Diego officials are preparing for a multi-day storm system expected to bring heavy rain from Monday through Thursday. City crews have been cleaning over 46,000 storm drains and clearing debris from channels like Chollas Creek to reduce flooding risks. Low-lying areas including Mission Valley and Sorrento Valley are particularly vulnerable during extended rain events.

Storm teams will monitor river levels and storm channels while maintaining more than 46,000 storm drains across the city. Crews have swept streets to prevent trash from washing into waterways and cleared tons of vegetation from drainage systems. Roads in flood-prone areas may close if necessary, with officials urging drivers to avoid these locations during heavy rainfall.

The city's Stormwater Department has prepared sandbags at 11 recreation centers across San Diego, with a 10-bag limit per household. Residents are advised to clear debris from drains, secure trash bins, and turn off irrigation systems. Emergency officials emphasize never driving through floodwaters and knowing evacuation routes. With preparations complete, the city encourages residents to take simple steps now to protect their homes and property.
