If traveling Sunday, avoid downtown and waterfront routes near Howard/Main to Great Highway — expect road closures and major transit detours for Bay to Breakers (May 17).
Expect very windy conditions Friday–Saturday postpone or avoid coastal activities and small-boat plans during the gale watch.
Be vigilant in retailers and transit hubs: keep bags zipped, wallet out of rear pockets, and limit distractions in stores with prior theft reports.
If you will be near schools or campuses, monitor local alerts — a recent Pacifica school lockdown was lifted but authorities advised avoiding the area while police responded.
