It claims the lives of about 20 people annually, according to the NWS. The threat of lightning becomes more pronounced as thunderstorms draw nearer, peaking when the storm is directly overhead and gradually waning as it moves away.<\/p>\n<p>To ensure your safety during a thunderstorm, consider the following recommendations:<\/p>\n<p>Lightning safety plan:<\/p>\n<p>When venturing outdoors, it\u2019s crucial to have a lightning safety plan in place.<br \/>\nStay vigilant by monitoring the sky for ominous signs and listening for the telltale sound of thunder. If thunder is audible, it\u2019s a clear indication of nearby lightning.<br \/>\nSeek a safe place to shelter, preferably indoors.<\/p>\n<p>Indoors safety measures:<\/p>\n<p>Once you\u2019ve found shelter indoors, abstain from using corded phones, electrical appliances, or plumbing fixtures, and refrain from approaching windows and doors.<br \/>\nLightning can follow conductive pathways, and these precautions reduce the risk of electrical surges.<\/p>\n<p>Wait for the all-clear:<\/p>\n<p>After the last lightning strike or thunderclap, wait at least 30 minutes before resuming outdoor activities.<br \/>\nLightning can strike even when a storm has seemingly passed, so exercise caution.<\/p>\n<p>When indoor shelter isn\u2019t available:<\/p>\n<p>If you find yourself outdoors without access to indoor shelter during a thunderstorm, take these steps to maximize your safety:<\/p>\n<p>Avoid open fields, hilltops, or ridge crests, which expose you to greater lightning risk.<br \/>\nSteer clear of tall, isolated trees and other prominent objects. In forested areas, stay close to lower stands of trees.<br \/>\nIf you\u2019re with a group, ensure individuals are spread out to prevent lightning current from transferring between people.<br \/>\nCamping in an open setting during a thunderstorm is strongly discouraged. If you have no alternative, set up camp in a valley, ravine, or other low-lying areas. It\u2019s crucial to note that a tent provides no protection against lightning.<br \/>\nDo not approach water bodies, wet objects, or metal items. While water and metal don\u2019t attract lightning, they conduct electricity effectively and can pose significant risks.<\/p>\n<p>In summary, when facing the threat of lightning, vigilance and preparedness are your best allies. By following these guidelines, you can significantly reduce the chances of lightning-related accidents and prioritize your safety.<\/p>\n<p>Navigating rainy roads: Safety tips for wet weather <\/p>\n<p>Heavy rainfall may lead to flooding if prolonged or if there is excessive runoff. Excessive runoff can be a result of saturated ground and\/or rainfall intensity. Follow these recommendations from the NWS to stay safe in heavy rain:<\/p>\n<p>Beware of rapid water flow:<\/p>\n<p>During heavy rain, avoid parking or walking near culverts or drainage ditches, where swift-moving water can pose a serious risk.<\/p>\n<p>Maintain safe driving distances:<\/p>\n<p>Use the two-second rule to maintain a safe distance from the car in front of you and allow an extra two seconds in heavy rain.<\/p>\n<p>Reduce speed and drive cautiously:<\/p>\n<p>If it is raining and the roads are wet, slow down. Take your foot off the accelerator and let your speed drop gradually. Never use the brakes suddenly because this may cause the car to skid.<\/p>\n<p>Choose your lane wisely:<\/p>\n<p>Stay toward the middle lanes \u2013 water tends to pool in the outside lanes.<\/p>\n<p>Visibility matters:<\/p>\n<p>Enhance your visibility in heavy rain by activating your headlights. Be particularly vigilant for vehicles in blind spots, as rain-smeared windows can obscure them.<\/p>\n<p>Watch out for slippery roads:<\/p>\n<p>Be extra careful during the first half hour after rain begins. Grime and oil on the road surface mix with water to make the road slippery.<\/p>\n<p>Keep a safe distance from large vehicles:<\/p>\n<p>Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and pass with caution.<\/p>\n<p>Mind your windshield wipers:<\/p>\n<p>Heavy rain can overload the wiper blades. When visibility is so limited that the edges of the road or other vehicles cannot be seen at a safe distance, it is time to pull over and wait for the rain to ease up. It is best to stop at rest areas or other protected areas.<\/p>\n<p>If the roadside is your only option, pull off as far as possible, preferably past the end of a guard rail, and wait until the storm passes. Keep your headlights on and turn on emergency flashers to alert other drivers of your position.<\/p>\n<p>In the face of heavy rain, these precautions can make a significant difference in ensuring your safety on the road. Remember to stay informed about weather conditions and heed guidance from local authorities for a secure journey.<\/p>\n<p>For more weather alerts in the Bay Area, visit <a href=\"https:\/\/www.mercurynews.com\/weather-advisory\/\" target=\"_blank\" rel=\"nofollow noopener\">Weather Advisories<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Marin Coastal Range, Coastal North Bay including Point Reyes National Seashore and North Bay Interior Valleys as well&hellip;\n","protected":false},"author":2,"featured_media":182622,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[30],"tags":[101,103,102,104,106,105,334],"class_list":{"0":"post-182621","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-san-francisco","8":"tag-san-francisco","9":"tag-san-francisco-headlines","10":"tag-san-francisco-news","11":"tag-sf","12":"tag-sf-headlines","13":"tag-sf-news","14":"tag-weather-advisory"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/182621","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=182621"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/182621\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/182622"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=182621"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=182621"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=182621"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
