High Wind Warning Tonight - November 12, 2025

Dear Customers,

The National Weather Service is warning San Francisco to prepare for high winds up to 35 mph, with gusts reaching 60 mph, starting at 10pm tonight through 10am tomorrow. Winds are expected to be especially strong on the hilltops and the west side of the City.

Given this serious forecast, DBI encourages you to take some basic precautions to keep your building, your neighbors and the people on the sidewalks below safe during high winds.

Before the storm

  • Close and latch any operable windows and remind your tenants to take this simple, but important step.
  • Remove all loose or unsecured objects from balconies, roofs or other outside areas. Holiday decorations and outdoor furniture may be especially vulnerable to the high winds.
  • If you see any cracks or signs of distress around a window, contact building management to help secure the opening.
  • If construction work is taking place at your building, scaffolding and construction equipment and materials should be secured on roofs and outside areas.

During the storm

  • If you see something of concern about a building, call 911 if it’s an emergency or there’s an injury.
  • Otherwise, file a report at 311 and the Department of Building Inspection (DBI) will send an inspector to investigate. DBI has a team of 24/7 on-call inspectors prepared to immediately respond to building-related incidents during storm events.

Thank you for your vigilance and please be safe.
