Part of Northern California under red flag warning
A red flag warning is now in effect for part of Northern California, the National Weather Service said.
Winds between 10 to 20 mph, and gusts of up to 30 to 40 mph are contributing to the fire weather conditions, along with low relative humidity, the NWS said.
The warning stretches from Redding to Modesto, and the NWS said the areas under the highest threat are the Sacramento Valley along and west of the Interstate 5 corridor, the adjacent coastal range and the northern San Joaquin Valley.

The 2025 FIFA Club World Cup Is About To Get A Lot Hotter
Marquinhos of Paris Saint-Germain cools down in the hot weather during the FIFA Club World Cup 2025 ... More group B match between Paris Saint-Germain FC and Club Atletico de Madrid at Rose Bowl Stadium on June 15 in Pasadena, Calif. While some teams – particularly those from milder European climbs – have already complained about oppressive heat at games across the United States through the first week of the tournament, forecasts are calling for conditions to worsen significantly over the next several days. So far, the heat has been mostly seasonal in June in the U.S., particularly on the Eastern Seaboard where the majority of tournament matches are being played. That has prompted some kidding from local observers of the tournament, who are accustomed to regularly playing through such conditions in domestic play as well as the currently ongoing Concacaf Gold Cup. But the next few days could be truly dangerous in places where group stage matches are scheduled. And possibly compounding matters are FIFA's decision the schedule the majority of those matches before sundown locally, to be shown in more favorable TV windows in Europe and elsewhere around the world. There are currently five group stage games scheduled where the forecast high is 94 degrees Fahrenheit or higher and the match is scheduled entirely. (All data is from as of Saturday evening.) Sunday Tuesday Wednesday Borussia Dortmund vs. Ulsan HD (Cincinnati) There are no current plans to reschedule kickoff times, though as recent weather delays have shown, that sort of thing is always subject to change. But part of the issue is that final group games from Monday to Thursday are scheduled tkick off simultaneously to avoid giving any team a competitive advantage on the final day of group play. So if one match is rescheduled for later in the day, presumably the corresponding other match in the group would also need to be. Of course, temperature is only part of the story. The heat index and WetBulb Globe Temperature (WBGT) use additional factors such as relative humidity and sun intensity to measure how adverse conditions are. But were these MLS fixtures, it appears likely they would be rescheduled to night kickoffs. According to information from the league's website published in 2016, matches will go into a delay if and when the WBGT rise above 92.3. Given that all of these kickoffs occur before sundown – and given that in the Eastern United States, heat and humidity go together – it's very likely conditions will exceed that threshold at least at some of these scheduled fixtures. Looking forward, there may be even more potential for heat to have extreme impact on the knockout phase. Of the 15 scheduled single-elimination matches, 11 are scheduled to kick off at 4 pm ET or earlier in outdoor conditions. Temperatures aren't expected to be quite as hot into early July as they are the first few days of the coming week, but summer forecasts in particular are turbulent, and another wave of extreme heat before the competition ends wouldn't be all that surprising.

Fire danger grows as heat continues across Colorado, cooler weather ahead
The first official weekend of summer is here, and it's been a hot one. Denver tied the record high of 99° on Friday and came just one degree shy of tying another record on Saturday. Sunday will bring more of the same, with high temperatures climbing into the low to mid-90s across much of the eastern plains. In the high country, highs will range from the 70s to 80s. The big change on Sunday is an increase in fire weather concerns. CBS Fire weather conditions will expand eastward to include much of the I-25 corridor. Elevated fire danger is expected, with wind gusts reaching 30 to 45 mph—a key ingredient for rapid fire growth. Relief from the heat is on the way. A cold front arrives Sunday night into Monday, bringing temperatures down into the upper 70s and low 80s to start the work week. Daily chances for showers and thunderstorms also return.

Los Angeles County firefighters prepositioned due to "critical fire weather"
With red flag warnings in place for critical fire weather in Los Angeles County on Saturday, state and city leaders have taken a proactive approach to the potential need for firefighters. National Weather Service officials issued the red flag warning on Saturday, which they expected to last from 1 p.m. until at least 5 a.m. on Sunday morning. Areas affected by the warnings include the I-5 corridor and the Antelope Valley, where NWS officials say "strong to damaging" winds, some of which could reach up to 65 mph, were expected. This, paired with low humidity in the area, could create dangerous fire conditions. In response, California Governor Gavin Newsom approved the prepositioning of some firefighting resources. "The Governor's Office of Emergency Services has approved the prepositioning of firefighting resources in Los Angeles County in response to Red Flag Warnings and critical fire weather conditions forecasted to impact Southern California through Sunday, June 22, 2025," said a release from Newsom's office. "This proactive approach has proven to be a critical component of California's wildfire response strategy, reducing response times and containing fires before they escalate into major incidents. These efforts ensure that both ground and air resources are ready to respond quickly, minimizing the potential impact of new fires." In January, a series of red flag warnings were issued due to similar weather conditions. The extremely high-powered winds and low levels of humidity created conditions that saw several devastating wild fires, including the Palisades and Eaton fires, break out and destroy thousands of homes and buildings.
