Wildfire Risk Likely To Increase Into Late September As Hot, Dry Weather Builds Across West

The western United States remains a tinderbox, and wildfire conditions may worsen as September weather patterns progress. A persistent northward bulge in the jet stream allowed temperatures to soar to well above average and at times record levels in parts of the West this summer. That same weather pattern may return later in September. Most of the large wildfires in California that have burned 875,000 acres as of Aug. 28 are now mostly contained. However, multiple large fires in the Northwest continue to burn with with substantially less containment.

Record-Hot August, Dry Year Leave High Fire Risk In County

This month will go down as San Diego’s hottest August on record. It was the second hottest month, any time of year, in city history. The month set or tied 15 daily records for either the highest maximum or minimum temperature. The August heat follows a similarly toasty July, making the July/August combination the second hottest in city history. And the heat comes near the tail end of the second driest rainfall season on record, dating back to 1850. The heat and the prolonged dryness set up the county for a challenging fall, which historically is when the region’s biggest and most destructive wildfires have struck.

Unusually Warm Southern California Ocean Helps Break Temperature Records in San Diego

Sea-surface temperatures along the coast of Southern California have grown unusually warm in the last month, contributing to record-breaking temperatures and uncomfortable humidity in San Diego.

The ocean temperatures warmed from a hot weather pattern in place across California this summer, which vaulted the state to its warmest July on record. The hotter-than-average conditions are due to a persistent area of high pressure in the upper atmosphere.

San Diego’s Daytime High Hits 80-or-Above Range for the 17th Straight Day

The daytime high in San Diego hit 83 degrees on Monday, the 17th straight day that the high was 80 or above, says the National Weather Service says.

And the same is likely to happen on Tuesday.

A high pressure system and unusually warm ocean temperatures are fueling the hot stretch, and there’s little relief in sight. Seasonal monsoonal moisture is expected to return on Wednesday and last until Friday. Thunderstorms are possible in the mountains.

Break in the Weather Helps California Firefighters Battle Massive Blazes Across State

Cooler, calmer weather is helping firefighters get a handle on battling the largest wildfires burning across California and preventing new blazes from getting out of control.

Temperatures are cooling slightly, and humidity is inching upward due to a weakened high-pressure system that forecasters say will persist through Tuesday.

San Diego Probably Just Had The Warmest August Night in City History

San Diegans, yes, your body thermostats are operating properly. The nights have been hot. Extremely hot. Record-breaking hot.

San Diego has just had what is likely to go down as the warmest August night in city history. The low after 12:01 a.m. on Thursday was 77 degrees. No other August night has been that warm, going back to 1874.

(National Weather Service forecasters did not expect the low to drop below 77 before midnight Thursday, which is the cut-off time for official daily records.)

Smoke Should Clear; Heat To Stay

Northwestern San Diego County got off to a smoky start Thursday after smoke from the Holy fire in Orange County drifted over the region Wednesday night. The weather pattern should clear out the smoke Thursday, but it will only add to the heat. The National Weather Service has issued an excessive heat warning, in effect until 8 p.m. Thursday, from the foothills to the coast. Highs at the beaches could reach the mid 90s, while the inland valleys could be as hot as 104. The culprit is a push of hot air from the east.

July Was The Hottest Month On Record In California, Record-Wettest In Mid-Atlantic

California experienced its hottest single month in 124 years of recordkeeping, according to NOAA’s monthly summary of United States climate released Wednesday. For the contiguous U.S. as a whole, it was the 11th-hottest July on record, with almost every state coming in warmer than average. The national average of 75.5 degrees Fahrenheit was 1.9 degrees above the 20th-century norm, said NOAA. In addition, several communities in California and adjacent Nevada had their all-time hottest single month.

California’s Destructive Summer Brings Blunt talk About Climate Change

At Scripps Pier in San Diego, the surface water reached the highest temperature in 102 years of records, 78.8 degrees. Palm Springs had its warmest July on record, with an average of 97.4 degrees. Death Valley experienced its hottest month on record, with the average temperature hitting 108.1. Park rangers said the heat was too much for some typically hardy birds that died in the broiling conditions. Across California, the nighttime brought little relief, recording the highest minimum temperature statewide of any month since 1895, rising to 64.9. California has been getting hotter for some time, but July was in a league of its own.

Third Heat Wave In A Month Begins Monday In San Diego
