If you are in a flood-prone area, move to high ground immediately. A flash flood is a sudden, violent flood that can develop in minutes to hours. It is even possible to experience a flash flood in areas not immediately receiving rain.<\/p>\n<p>Flood warning: Take action!<\/p>\n<p>A flood warning is issued when flooding is imminent or already underway.<\/p>\n<p>Flood advisory: Be aware:<\/p>\n<p>A flood advisory is issued when flooding is not expected to reach a level that warrants a warning. Nonetheless, it can still cause considerable inconvenience and, without exercising caution, potentially lead to situations that threaten life and\/or property.<\/p>\n<p>Flood watch: Be prepared:<\/p>\n<p>A flood watch is issued when conditions are favorable for flooding. It doesn\u2019t guarantee flooding will occur, but it indicates the possibility exists.<\/p>\n<p>When floods strike: Guidelines from the NWS for your protection<\/p>\n<p>Floods can pose a significant threat, especially if you live in a flood-prone area or find yourself camping in a low-lying region. To ensure your safety, the NWS offers essential flood safety guidelines:<\/p>\n<p>Move to higher ground:<\/p>\n<p>If you reside in a flood-prone region or are camping in low-lying terrain, the first step to safety is relocating to higher ground.<\/p>\n<p>Follow evacuation orders:<\/p>\n<p>When local authorities issue an evacuation order, promptly comply. Before leaving, secure your home by locking it.<\/p>\n<p>Disconnect utilities and appliances:<\/p>\n<p>If time permits, disconnect your utilities and appliances. This precaution minimizes electrical hazards during flooding.<\/p>\n<p>Avoid basements and submerged areas:<\/p>\n<p>Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.<\/p>\n<p>Swift evacuation for your safety:<\/p>\n<p>If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be electrically charged.<\/p>\n<p>Refrain from walking in floodwaters:<\/p>\n<p>Never attempt to walk through floodwaters, even if they appear shallow. Just 6 inches of fast-moving water can forcefully sweep you off your feet.<\/p>\n<p>Seek high ground if trapped:<\/p>\n<p>Should you become trapped by moving water, reach the highest point possible and dial 911 to contact emergency services.<\/p>\n<p>When heavy rain occurs, there is a risk of flooding, particularly in low-lying, flood-prone areas. It is important to never attempt to drive through water on the road, regardless of how deep it appears. According to the NWS, as little as 12 inches of rushing water can sweep away most vehicles. Prioritize your safety by staying informed and prepared.<\/p>\n<p>For more weather alerts in the Bay Area, visit <a href=\"https:\/\/www.pressdemocrat.com\/weather-advisory\/\" target=\"_blank\" rel=\"noopener nofollow\">Weather Advisories<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"North Bay Interior Valleys and San Francisco Bay Shoreline, as well as San Francisco County, are under a&hellip;\n","protected":false},"author":2,"featured_media":117416,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[184,7,9,8,56752,61656,266],"class_list":["post-117415","post","type-post","status-publish","format-standard","has-post-thumbnail","category-california","tag-bay-area","tag-california","tag-california-headlines","tag-california-news","tag-flood-warning","tag-january-2026","tag-northern-california"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/117415","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=117415"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/117415\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/117416"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=117415"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=117415"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=117415"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
