In San Francisco, there is already concern about potential impacts from rain and winds during the storms expected this week. San Francisco’s Department of Emergency Management said it has been coordinating with the National Weather Service and other agencies since earlier this week to prepare for the storms. As of Sunday night, rain started to come down hard onto San Francisco streets, where some roadways already saw minor pools of standing water. The Department of Emergency Management is urging residents to prepare immediately by securing loose items, charging devices, and getting ready for possible power outages. Residents should also expect possible delays in transit and are advised to allot extra travel time. Even if you’re not traveling on the roads, you may still face travel delays. At the San Francisco International Airport, the duty manager told NBC Bay Area that the airport experienced weather-related ground delays for much of the day on Sunday, and by Sunday night, the average ground delay was four hours and 14 minutes. The duty manager also said that because of the winds coming from the south, aircraft are currently directed to take off and land in a different direction than normal. San Francisco city crews have been working through the weekend to keep leaves out of storm drains and to respond to downed trees. In the Amazon Crocker neighborhood, one large portion of a tree came down on Drake Street following what neighbors said was several hours of light to moderate rain. Neighbors said the broken section of the tree blocked off the entire street. San Francisco Fire crews responded shortly after and were able to clear the roadway. No people were hurt or property was damaged in this incident. “This is one of the things that San Francisco people should be worried about: trees coming down, the drains getting full, you know — clean the drains, and just keep an eye out for each other,” said Xavier Haro, who lives right across from the tree that fell. If you see a downed tree in San Francisco, call 311 to report it if it is not an emergency issue. If it is an emergency, call 911.
