This week could bring Southern California its most sweltering temperatures of the year \u2014 a heat wave made all the more miserable, and dangerous, by oppressive muggy conditions and little nighttime relief. <\/p>\n

\u201cThis looks to be the hottest stretch so far this year,\u201d said Ryan Kittell, a meteorologist with the National Weather Service\u2019s Oxnard office. <\/p>\n

And it\u2019ll be quite a stretch. The mercury could hit triple digits across much of the Southland Tuesday through Monday. <\/p>\n

Over the next week, temperatures could hit 109 in Paso Robles, 108 in Lancaster, 106 in Canoga Park, 102 in Santa Clarita, 99 in Covina, 92 in downtown Los Angeles and 87 in Long Beach. Temperatures could also exceed 100 degrees in the Inland Empire and some parts of San Diego County\u2019s interior valleys and surpass 110 degrees in the deserts, said Sebastian Westerink, meteorologist with the weather service\u2019s San Diego office.<\/p>\n

Here are five things you need to know about this potentially dangerous weather:<\/p>\n

Oppressive and widespread heat<\/p>\n

A heat advisory, signifying oppressive heat is imminent or occurring, will be in place across Southern California, including much of Los Angeles, San Diego, Orange, Riverside, San Bernardino, Ventura and Santa Barbara counties. (Some beaches were excluded.)<\/p>\n

The National Weather Service\u2019s heat advisory was slated to begin 10 a.m. Wednesday and last through 8 p.m. Monday.<\/p>\n

The expected duration of the heat wave \u2014 at least several days, if not longer \u2014 \u201ccan really be concerning,\u201d said Robbie Munroe, meteorologist with the weather service\u2019s Oxnard office. <\/p>\n

\"Peak Little overnight relief<\/p>\n

Exacerbating the misery will be the lack of cooling temperatures overnight. The L.A. Basin may see low temperatures of only about 70 degrees. <\/p>\n

\u201cThat means the evenings will remain quite hot, and even overnight, when people might open their windows to try to cool off their homes, you\u2019re not going to see a whole lot of help there in a lot of areas,\u201d Munroe said. <\/p>\n

Forecasters urged people to limit outdoor activities to just the early morning hours if possible, to stay in air conditioned spaces in the afternoon and evening hours, and take frequent rest breaks. If it\u2019s necessary to be outdoors, residents should stay hydrated and stay in the shade as much as possible. Children and pets should never be left unattended in vehicles. <\/p>\n

Fire weather returns<\/p>\n

Officials warned of elevated fire danger across large swaths of Southern California starting Tuesday, with a high risk of fast-moving and \u201cplume-dominated\u201d fires driven by heat and instability. Such blazes have large vertical growth and can spread rapidly even when not driven by the wind.<\/p>\n

But wind-driven fires will still be a risk \u2014 especially for southwestern Santa Barbara County, where expected sundowner winds down the southern slopes of the Santa Ynez Mountains could cause a fire to explode if there\u2019s ignition.<\/p>\n

\"Fire Potentially dangerous ocean conditions<\/p>\n

Officials warned of hazardous conditions \u2014 such as high surf and strong rip currents \u2014 across much of the Southern California coastline. <\/p>\n

There\u2019s a persistent swell coming from the south, forecasters said, with peak surf as high as 4 to 8 feet. The hazardous surf is being sent from tropical storm systems south of California, including Tropical Storm Fausto and the remnants of Tropical Storm Elida. <\/p>\n

\u201cAlways swim near lifeguards. Check in with and ask advice from lifeguards before entering the water,\u201d the weather service said. \u201cStay off rock jetties!!!\u201d<\/p>\n

A number of Californians have died along the coast this summer, including a 5-year-old girl<\/a> from San Bernardino who was swept<\/a> into the ocean by powerful waves in Laguna Beach. On one recent day alone, Newport Beach lifeguards made more than 100 rescues. <\/p>\n

\"Map Heat may stick around<\/p>\n

Heat might persist into the last week of July. There\u2019s a 60% to 80% chance of above-normal temperatures between July 27 and Aug. 2, Munroe said.<\/p>\n","protected":false},"excerpt":{"rendered":"This week could bring Southern California its most sweltering temperatures of the year \u2014 a heat wave made…\n","protected":false},"author":2,"featured_media":406439,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[2491,3802,2881,99910,48,52,51,47,50,49,63,30713,60,44427,14291,84,102839,1009,36898,162949,72],"class_list":["post-406438","post","type-post","status-publish","format-standard","has-post-thumbnail","category-los-angeles","tag-degree","tag-fire","tag-forecaster","tag-heat-advisory","tag-la","tag-la-headlines","tag-la-news","tag-los-angeles","tag-los-angeles-headlines","tag-los-angeles-news","tag-los-angeles-times","tag-meteorologist","tag-national-weather-service","tag-robbie-munroe","tag-san-bernardino","tag-san-diego-county","tag-socal-heat-wave","tag-southern-california","tag-temperature","tag-tropical-storm-system","tag-year"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/406438","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=406438"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/406438\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/406439"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=406438"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=406438"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=406438"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
