Powerful flash flooding swept through the Grand Canyon over the weekend, crippling a key water line and prompting the National Park Service to impose emergency water restrictions as crews continued searching for missing hikers.

The NPS said stage four water restrictions will take effect at 12:00 p.m. Monday after Saturday’s flooding caused “extensive damage to infrastructure,” including the Transcanyon Waterline, the main system that supplies water to the park. Officials said one person was killed and as many as 15 others may be missing, though they emphasized that the number remains an estimate.

Park officials said the body of a 46-year-old man was recovered from the Colorado River on Sunday night. His name has not been released publicly.

The National Park Service has asked the public to share any information that could help locate the 15 people believed to be missing.

“The National Park Service is asking anyone who knows of hikers or backpackers who were in the inner canyon along the Bright Angel Creek corridor on August 29, as well as anyone who had a campground reservation in the affected corridor, to provide information to the National Park Service Investigative Services Branch,” NPS said in a statement.

Park officials say they have so far evacuated at least 62 people since the Saturday flooding.

The stage 4 water restrictions affecting the rest of the park include forced dry camping with no access to water spigots, the temporary closure of overnight lodgings, and a strict no-fire rule for the South Rim and inner canyon areas.

The flooding struck Bright Angel Canyon and the Phantom Ranch area on Aug. 29, according to NPS, which added that nearly all footbridges spanning Bright Angel Creek were destroyed.

Arizona Gov. Katie Hobbs said state emergency officials are coordinating with federal and local authorities as the search continues.

“My heart is with the families and loved ones of every person unaccounted for after the flash flooding at the Grand Canyon,” Hobbs wrote on X. “DEMA is coordinating with NPS and Coconino County Emergency Management to support search and recovery efforts.”

Arizona Secretary of State Adrian Fontes called the flash flooding “devastating” and thanked first responders for searching for those still unaccounted for and evacuating others from the affected area.

“The physical damage includes a historic lodge near the bottom of the site and untold environmental upheaval,” Fontes said in a statement. “I send my prayers to the community as the search for those unaccounted for continues.”

Howard Stern is bringing his SiriusXM show back for a new season on September 14 — and, in a first for the longtime radio titan, episodes will also be available to stream on HBO Max.

SiriusXM announced Stern’s new HBO Max deal in a press release shared with Page Six on Monday.

“For the first time, the ‘King of All Media’ will bring his signature, long-running SiriusXM show to HBO Max by adapting his live SiriusXM show into a streamable episode for HBO Max, along with periodic extras,” the release stated.

The Howard Stern Show, which first launched on Sirius in 2006, will make its HBO Max debut on September 17. New episodes are set to arrive on the streaming platform every Thursday.

“Howard’s new series on HBO Max takes him to the pinnacle of prestige television and gives his fans a long-desired ‘seat in the studio’ to see what they just heard,” the announcement added.

“As fans hear his live show on SiriusXM, 40 cameras will capture the conversation for a version of the show then adapted into a streamable episode for HBO Max with periodic extras.”

Scott Greenstein, SiriusXM’s President and Chief Content Officer, said in a statement, “There’s simply no one like Howard, and the start of his new season is another exciting chapter in an extraordinary run. For more than two decades at SiriusXM, he’s continued to evolve, surprise audiences and deliver the kind of conversations and moments that only Howard can.”

Greenstein added, “We are proud that Howard chose to continue with SiriusXM through 2028 for his exclusive live show and deep library of classic Howard, and that Howard, HBO Max and SiriusXM have now teamed up to create a compelling new video version of his show.” 

Sirius also confirmed that Stern’s Howard 100 channel will have “a new lineup” including “Wrap Up Wednesday,” an expanded version of his “Wrap Up Show” hosted by Gary Dell’Abate and Jon Hein.

There will also be “new ways to hear [Stern’s] multi-decade library of past shows,” according to the press release.

The new deal comes on the heels of the news that Stern’s Howard 101 SiriusXM channel has been dropped after a dozen staffers were laid off earlier this summer.

This story is developing…

Hurricane forecasters are keeping a close watch on two developing weather disturbances in the Atlantic basin, with both systems tracking in the general direction of the US.

The nearer concern is Invest AL97, which could briefly strengthen into a tropical depression or tropical storm before it moves ashore.

As of Monday morning, the system was located more than 98 miles south of Louisiana and was drifting slowly toward the west-northwest.

Satellite observations indicated that AL97’s circulation was still poorly defined, though the disturbance was generating winds of about 29 to 35mph and environmental conditions remained supportive of additional development.

Forecasters said Invest AL97 is expected to approach the Upper Texas coast or southwestern Louisiana late tonight or by Tuesday morning.

Tropical storm watches or warnings could be issued later Monday, while heavy rain is expected along parts of both coastlines regardless of whether the system develops.

The National Hurricane Center (NHC) is also tracking the remnants of Tropical Storm Dolly as they race westward across the Caribbean toward Florida.

Dolly is unlikely to redevelop over the next day or two, but its moisture is expected to increase Florida’s rain chances later this week.

An Air Force Reserve reconnaissance aircraft is scheduled to investigate the system in the Gulf later this morning. 

Forecasters said it has a high chance of becoming a tropical cyclone within the next seven days. 

The NHC gives it a 70 percent chance of development over both the next two and seven days. The next named storm would be Edouard.

Chicago & Midwest Storm Chasers said on X: ’97L continues to look increasingly organized this morning, with deep convection exploding around the circulation and persistent lightning near the center. 

‘The current satellite presentation appears more organized than some hurricane-model guidance has been depicting.’

Farther east, the remnants of Tropical Storm Dolly are producing heavy showers and thunderstorms from Puerto Rico across the Virgin Islands and northern Leeward Islands.

The system remains a strong tropical wave but does not have a fully formed center of circulation. 

That makes redevelopment unlikely over the next day or two as it races west to west-northwest at about 25mph.

Conditions could become slightly more favorable by midweek as Dolly approaches the Gulf.

However, its chances of reforming remain near zero over the next 48 hours and just 20 percent across the next seven days.

Even if Dolly never redevelops, Florida could still feel its effects.

The wave could drag more tropical moisture across the state and combine with favorable conditions higher in the atmosphere, bringing more widespread rain and stronger afternoon storms later this week. 

It could also keep the rip-current risk elevated at area beaches, depending on changes in air pressure and whether long-period swells reach the coast.

East Central Florida is facing a hot, muggy and stormy week, with forecasters warning of heavy rain, damaging wind gusts and possible localized flooding.

Scattered to widespread thunderstorms are expected to develop from late Monday morning through the evening, according to Indian River County Weather. 

Rain chances will range from 50 to 60 percent across the region, including a 50 percent chance around Vero Beach.

The strongest storms could unleash wind gusts of 40 to 50mph, frequent lightning and torrential rain. Slow-moving storms could dump large amounts of water over isolated areas, triggering flash flooding.

Temperatures will reach 89 to 92 degrees, but high humidity could make it feel like 100 to more than 105 degrees.

Conditions could deteriorate further Wednesday and Thursday as the remnants of Tropical Storm Dolly pass near Florida and pull more moisture into the state. 

Parts of the region face a marginal, Level 1 out of 4, risk of excessive rainfall Thursday.

Conditions offshore should remain relatively manageable, with east-to-southeast winds of five to ten knots, about six to 12mph, and waves of two to three feet. However, thunderstorms will remain a daily threat for boaters.

Rain chances could ease slightly over the weekend but are expected to remain above normal as temperatures climb into the low- to mid-90s.

Thirteen people were injured early Monday when an employee shuttle bus slammed into a concrete barrier at Newark Liberty International Airport in New Jersey, according to local media reports.

The crash occurred shortly after 3 a.m. on the Terminal B Departures Level 3 roadway, News 12 New Jersey reported.

Authorities said three people were seriously hurt and 10 others suffered minor injuries, according to the report. None of the injuries was believed to be life-threatening.

Video obtained by News Media showed the employee shuttle bus heavily damaged and still lodged against the concrete barrier after the Newark Airport crash. The front of the vehicle appeared crushed, with shattered glass visible around the bus door and windshield.

Police tape surrounded the crash site as first responders worked nearby.

The injured were transported to area hospitals for evaluation and treatment, according to WABC-TV.

The crash prompted authorities to close the Terminal B Departures Level 3 roadway as crews worked to clear debris from the area.

The Port Authority Police Department advised passengers departing from Terminal B to be dropped off on Level 2 because of the police activity.

Authorities have not released the cause of the crash.

The investigation is ongoing.
