National Weather Service

The National Weather Service issued an advisory Friday on the possibility of minor tidal overflows along the coast. Newport officials were not alarmed by the notice. National Weather Service forecaster Robert Balfour said overflows were possible through today. He said high surf generated by a south swell could combine with an expected high tide to allow ocean water to rise above seawalls. Thursday night, the tide around Newport rose to 7 feet, 5 inches, said Rick Greaney of the Newport Beach general services department.

GLENDALE ? Just a week after temperatures raced toward triple digits, Glendale bundled up Friday in the face of plummeting temperatures and a light rainfall that spread drizzle across the region. The drastic change in temperatures ? from May 17, when the National Weather Service recorded a high of 98 degrees in Glendale to Friday, when 64 degrees was the highest point in the mercury ? is a result of an unusual weather pattern that originated in the Great Basin region near Wyoming, weather specialist Stuart Seto said.

High wind and red flag warnings were issued Wednesday in anticipation of gusts that could reach 80 mph and create what a spokeswoman called “explosive” fire conditions in Southern California. Intense Santa Ana winds are expected to begin hitting mountain passes in Los Angeles, Orange and Ventura counties Wednesday afternoon and continue into Friday, the National Weather Service said. Advisories warn that the winds could take down trees and power lines, spread debris and create hazardous driving conditions.

After an unseasonably dry and warm winter so far, Southern Californians will be treated to some cooler temperatures this week and maybe even some rain later on, National Weather Service officials said Tuesday. Rain could come as early as Friday and last into the weekend, but the amount hasn't been forecast yet, said Bonnie Bartling, a weather specialist with the National Weather Service. January temperatures have averaged a high of 73 degrees, and one day rose to 86 degrees.

Cloudy skies today will bring cooler temperatures and possible rain showers, according to the National Weather Service. There's a 20% chance of rain in the tri-city area today, but the potential for wet weather is expected to dissipate by Tuesday morning. By Wednesday, sunny skies and moderate Santa Ana winds return, gradually pushing temperatures back into the 80s for the weekend, according to the weather service.

Clear skies may be back, but don't expect daytime temperatures to get past the low-70s through Thursday, when another weather system promises to bring a fresh round of rain, according to the National Weather Service. Overnight lows will also remain chilly ahead of the next storm, which is expected to roll in Thursday evening and produce rain through Sunday. Snow is also likely for the higher elevations of Angeles National Forest. -- Jason Wells , Times Community News Twitter: @JasonBretWells Image: National Weather Service

Temperatures were expected to cool down Monday from the weekend, reaching the 70s along the coast, and the 80s inland, according to the National Weather Service. The cooler temperatures should prevail through Tuesday and warm up Wednesday. The end of the week could bring colder-than-normal temperatures and even a “slight” chance of showers, said Bonnie Bartling of the National Weather Service. By Friday, low-pressure troughs could cause temperatures to dip as much as 15 to 20 degrees, she said.

The National Weather Service has issued a red flag fire warning from 10 p.m. Thursday to 6 p.m. Friday for mountain areas in Los Angeles County because of expected Santa Ana winds. The warning, which signifies critical brush-fire danger, is for inland and coastal mountain areas and the Santa Clarita Valley, where the dry northeasterly winds are expected to blow up to 40 mph. The winds, coupled with low relative humidity, could result in explosive fire conditions, the Weather Service said.

Glendale residents took time out from a hot day to go swimming during recreational swim hours at the Hoover High School pool Wednesday. The high temperature for Glendale was 96 degrees Wednesday, National Weather Service weather specialist Stuart Seto said. Partly cloudy skies are expected as a moisture surge from the southeast is expected to move through Glendale over the weekend and through Tuesday. A new safety tip released by the National Weather Service is to reduce protein intake during hotter days.

A dense fog advisory remains in effect until 9 a.m. as morning commuters navigate freeways clogged by traffic accidents. The National Weather Service said dense morning fog could reduce visibility to one-quarter mile or less as a marine layer that's "not really playing by the rules" and low clouds inundate the region's valleys. Conditions should clear up by midday as a weak high-pressue system moves in, bringing with it a slight warming trend heading into the weekend, according to the weather service.

Red flag warnings were issued Wednesday across Southern California as heat and dry winds were expected to turn Los Angeles and Ventura County mountains and valleys into a tinderbox. The National Weather Service said the red flag warnings would be in effect through Thursday for the mountains of Los Angeles and Ventura counties, the Santa Monica Mountains, the San Fernando and Santa Clarita valleys and Ventura County valleys, the L.A. Times reported. Temperatures on Friday could rise past 100 degrees from Burbank to Pasadena, according to the weather service.

A combination of high pressure and offshore winds should send temperatures soaring later this week, according to the National Weather Service. After hitting the upper 70s on Wednesday, highs in downtown Los Angeles are expected to be well into the 80s for the rest of the week, according to Stuart Seto of the National Weather Service. Seto said the peak will likely come on Friday, which should see a high of 89 degrees downtown. In the Burbank-Glendale-Pasadena region, temperatures are expected to following a similar trajectory, possibly hitting 90 degrees on Saturday, according to the weather service.

Easter Sunday will be cloudy with possibly a few sprinkles, but forecasters have toned down their predictions of a rainy holiday. The storm system moving through Southern California is not carrying as much moisture as initially thought, National Weather Service meteorologist Kathy Hoxsie told the L.A. Times. The chance of rain on Sunday has been revised down to 20% from earlier forecasts of 30% to 50%. No rain is in the forecast for Monday. If it does rain, expect only a light drizzle.

A cold, blustery storm originating from the Gulf of Alaska is expected to move down the California coast Tuesday, creating traffic headaches in some places, authorities warned. Possible thunderstorms were expected to affect most of the Southland, bringing between one-tenth to half an inch of rain in most areas, the L.A. Times reported. Snow could fall as low as 1,500 feet, and there was high potential for icy roadways, including Interstate 5 from the Grapevine to the Santa Clarita Valley, according to the National Weather Service.

A cold low-pressure system moving south should reach the Los Angeles area Thursday evening, bringing with it the chance of rain and cooler temperatures through Friday night, according to the National Weather Service. The system is expected to bring low-elevation snow to local mountains that could linger through Saturday, Andrew Rorke, a meteorologist with the National Weather Service, told the L.A. Times. Snow levels could reach as low as 3,000 feet by Friday morning, which could create hazardous driving conditions, especially around Interstate 5 through the Grapevine, Rorke said.

A cold front from Canada that has settled in Southern California is expected to stick around for days, bringing snow flurries, scattered showers and low temperatures, forecasters said. Temperatures were expected to stay in the 50s across much of the region on Thursday, warming slightly throughout the day but staying chilly, said meteorologist Cathy Hoxsie of the National Weather Service in Oxnard. That includes the region from Burbank to Pasadena, where temperatures likely won't get past the mid-50s until next week, according to the weather service.

Cool and breezy conditions are expected to give way to another rainstorm later this week, but forecasters say it should be mostly clear and brisk by New Year's Day and the all-important Tournament of Roses Parade in Pasadena. Gusty northwest winds were expected for some areas through Thursday morning with most of the region experiencing fair weather Thursday and Friday, said experts with the National Weather Service in Oxnard. Many areas will experience 15- to 25-mph winds, they said, and the Antelope Valley and the mountains should see west to northwest winds of up to 45 mph. A winter weather advisory was issued for Thursday until 10 a.m., with blistery snow showers expected on north facing mountain slopes in Los Angeles and Ventura counties.

A weather system blowing into the region today will bring with it a chance of rain and cooler temperatures through the weekend, forecasters say. As the cloud cover builds, expect a 20% chance of rain in the Burbank-Glendale-Pasadena region Thursday night, according to the National Weather Service. The threat of rain will increase heading into the weekend, with a 50% chance of precipitation on Saturday before starting to taper off Sunday into next week. The cloud cover will also push daytime temperatures down into the 50s, according to the weather service.

A red flag warning has been issued until 6 p.m. Tuesday for parts of Los Angeles County, including local mountains and the Santa Clarita Valley, as wind gusts and dry conditions increase the threat of fire. Wind gusts on Monday could reach 50 mph in the mountains before starting to subside on Tuesday, according to the National Weather Service. Temperatures in the tri-city area are expected to warm into the mid-80s through Wednesday before clouds return, bringing with them a 30% chance of rain Thursday evening, the weather service said.

Weather forecasters have issued red flag warnings for much of the Southland for what "will likely be the strongest and most widespread Santa Ana wind event of the season. " "These critical fire weather conditions combined with very dry fuels will bring extreme fire danger to the Southland," the National Weather Service said in a statement Wednesday. Red flag fire warnings signaling extreme wildland fire conditions have been issued for Southern California counties because of Santa Ana winds of up to 65 mph that are expected to blow across the region.
