1Check flights and SFO alerts before travel and allow extra time — Runway 1R is closed for six months and the airport expects some flights (≈10%) to see delays, mainly 9am–9pm (Source: SFist — Six-Month Runway Closure at SFO May Cause Some Delays (2026-03-30)).
2Avoid walking alone at night in neighborhoods with recent violent incidents (SoMa, Sunnydale) and exercise caution near Stanford/Mayfield Ave after a reported armed sexual assault (Source: SFist — One Man Murdered, Two Assaulted in SoMa (2026-03-29) SFist — Jogger Sexually Assaulted By Armed Man Near Stanford University Campus (2026-03-30)).
3Expect interruptions to normal emergency response access: carry a charged phone, share plans with companions, and identify staffed businesses or public places to seek help if you cannot reach 911 (Source: SFist — Day Around the Bay: SF's 911 System Briefly Has Difficulty With Cellphone Calls (2026-03-31)).
