San Diego Unified says maintenance crews are clearing roof drains and storm lines, removing debris around drainage channels, inspecting slopes and trees, and staging sandbags, pumps and other flood-control equipment ahead of potentially severe El Niño weather.

Student lessons: El Niño Explorer Week, November 2–6

Campus work: Drain clearing, site inspections and flood-protection supplies

Family alerts: The district is asking families to update school contacts and sign up for regional emergency notifications

Schools and students prepare together

The district’s science team will lead a week of lessons on El Niño’s causes, regional effects and safety steps. KPBS reports that officials identified 10 campuses in flood-prone areas and said school police are developing site-specific plans for severe weather.

San Diego Unified also says some facilities could serve as temporary evacuation sites or shelters if local emergency agencies activate them. The district cautions that families should rely on official announcements before going to a school during an emergency.
