Downtown Los Angeles and Long Beach could see a high of 96 to 98 degrees, and communities farther inland and into the valleys could expect temperatures to reach more than 105.<\/p>\n<p>There will be little relief at night, when the region usually cools down. Low temperatures for Tuesday evening will probably stay in the mid-70s across the Los Angeles Basin, and weather forecasters say Wednesday might be even warmer.<\/p>\n<p>\u201cThe still-lingering moisture from Marie, combined with the heat, will add to the heat discomfort and create added heat stress,\u201d said David Gomberg, lead meteorologist at the National Weather Service in Los Angeles-Oxnard, which issued <a class=\"link\" href=\"https:\/\/forecast.weather.gov\/showsigwx.php?warnzone=CAZ354&amp;warncounty=CAC111&amp;firewxzone=CAZ354&amp;local_place1=2%20Miles%20E%20Oxnard%20CA&amp;product1=Heat+Advisory&amp;lat=34.1975&amp;lon=-119.176\" target=\"_blank\" rel=\"nofollow noopener\">a heat advisory<\/a> for Wednesday and Thursday and is on alert to ramp up the warnings if the week gets worse.<\/p>\n<p>\u201cIf the clouds don\u2019t materialize, then Wednesday could be a real problem, and temperatures could really jump up,\u201d said Gomberg, who reminded people to drink plenty of fluids, stay in air-conditioned rooms and check up on vulnerable relatives and neighbors.<\/p>\n<p>            <img class=\"image\" alt=\"People walk through a flooded street.  \"   width=\"1200\" height=\"800\" src=\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2026\/09\/1788825851_413_.jpeg\" decoding=\"async\" loading=\"lazy\"\/>         <\/p>\n<p>People walk through a flooded street during hide tide on Ocean Boulevard on the Alamitos Peninsula in Long Beach.<\/p>\n<p>(Ronaldo Bola\u00f1os \/ Los Angeles Times)<\/p>\n<p><a class=\"link\" href=\"https:\/\/forecast.weather.gov\/showsigwx.php?warnzone=CAZ354&amp;warncounty=CAC111&amp;firewxzone=CAZ354&amp;local_place1=2%20Miles%20E%20Oxnard%20CA&amp;product1=High+Surf+Advisory&amp;lat=34.1975&amp;lon=-119.176\" target=\"_blank\" rel=\"nofollow noopener\">High surf<\/a> and <a class=\"link\" href=\"https:\/\/forecast.weather.gov\/showsigwx.php?warnzone=CAZ354&amp;warncounty=CAC111&amp;firewxzone=CAZ354&amp;local_place1=2%20Miles%20E%20Oxnard%20CA&amp;product1=Coastal+Flood+Advisory&amp;lat=34.1975&amp;lon=-119.176\" target=\"_blank\" rel=\"nofollow noopener\">coastal flooding<\/a> advisories also remain in place until 11 p.m. Tuesday, with weather officials urging extreme caution as the ocean continues to churn from the remnants of Tropical Storm Marie. <\/p>\n<p>The rip currents and massive surf are capable of capsizing small boats, knocking people off jetties and pulling swimmers out to sea.<\/p>\n<p>\u201cAnybody who\u2019s inexperienced needs to stay away from the surf zone right now.

That\u2019s really dangerous, and that\u2019s why we use the headline \u2018potentially life-threatening rip currents.\u2019 \u201d<\/p>\n<p>In Malibu, waves at Zuma Beach broke as high as 12 feet over the weekend.

Some parts of Los Angeles County received more than 1.25 inches of rain on Sunday.<\/p>\n<p>            <img class=\"image\" alt=\"A man carries beach towels out of a flooded garage.\"   width=\"1200\" height=\"767\" src=\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2026\/09\/1788825854_70_.jpeg\" decoding=\"async\" loading=\"lazy\"\/>         <\/p>\n<p>Resident David Black carries beach towels out of his flooded garage on the Alamitos Peninsula in Long Beach. <\/p>\n<p>(Ronaldo Bola\u00f1os \/Los Angeles Times)<\/p>\n<p>Across Los Angeles County, public health officials <a class=\"link\" href=\"https:\/\/publichealth.lacounty.gov\/phcommon\/public\/eh\/water_quality\/beach_grades.cfm\/\" target=\"_blank\" rel=\"nofollow noopener\">urged beachgoers to avoid swimming<\/a> in the ocean through Wednesday because of  potential bacteria spikes from the rain.<\/p>\n<p>Topographically, Los Angeles County is like a giant bowl tilted toward the sea. Whenever it rains, <a class=\"link\" href=\"https:\/\/www.latimes.com\/california\/story\/2019-12-27\/ocean-swimming-after-rain-q-and-a\" rel=\"nofollow noopener\" target=\"_blank\">water rushes down streets and sidewalks<\/a> \u2014 picking up any trash, pesticides, dog poop and other fecal matter in its way. Unlike our sewage, which is filtered through treatment facilities before it\u2019s discharged, this mix of rainwater and debris flushes straight into the ocean through a network of storm drains and concrete-lined rivers.<\/p>\n<p>A good rule of thumb is to wait 72 hours after it rains before going into the ocean. Some scientists recommend five days, especially if the beach is close to an area where a river or an outfall dumps into the ocean.<\/p>\n","protected":false},"excerpt":{"rendered":"Days of more intense weather are ahead \u2014 extreme heat and high humidity \u2014 after a dramatic weekend&hellip;\n","protected":false},"author":2,"featured_media":456684,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[100781,77926,180185,2641,39930,180184,48,52,51,131,47,50,49,63,21659,62,36898,178292,18060,316,72],"class_list":["post-456683","post","type-post","status-publish","format-standard","has-post-thumbnail","category-los-angeles","tag-cold-water","tag-david-gomberg","tag-dramatic-weekend","tag-foot","tag-high-surf","tag-higher-than-high-tide","tag-la","tag-la-headlines","tag-la-news","tag-long-beach","tag-los-angeles","tag-los-angeles-headlines","tag-los-angeles-news","tag-los-angeles-times","tag-ocean","tag-rain","tag-temperature","tag-tropical-storm-marie","tag-wave","tag-wednesday","tag-year"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/456683","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=456683"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/456683\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/456684"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=456683"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=456683"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=456683"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
