WASHINGTON (AP) – Get ready for the annual fall ritual of turning back your clocks by one hour, and relish that extra hour of sleep this weekend. Daylight saving time is ending and it’s back to standard time for most people in the United States. The change comes at 2 a.m. local time Sunday, and the shift moves one hour of daylight to the morning from the evening.

Residents of Hawaii, most of Arizona and some U.S. territories don’t need to fiddle with their clocks because those places don’t observe daylight saving time. Daylight saving time returns at 2 a.m. local time on Sunday, March 12.

Remember, when we switch to Standard Time, “Fall back” one hour.

(Update 7:25-a.m.: Right lane open westbound on I-80 but traffic is heavy and slow)

One person has been confirmed deceased as the result of a fiery accident involving two semi tractor-trailers this morning, on Interstate 80 eastbound in Cass County. A second person was transported by Medivac Ambulance to the Cass County Memorial Hospital, in Atlantic. No names have been released. The Atlantic Fire Department was called the scene of the crash just east of the Highway 71 exit near the Nishna River Bridge, at around 5:30-a.m.

The road was completely blocked at the Nishna River bridge and traffic is being re-routed. Eastbound traffic is being directed south at Highway 71 to Highway 83 and then east to Anita. Westbound traffic was down to the right lane only as of 7:25-a.m. but traffic is extremely backed-up.

Initial reports from authorities at the scene indicated one of the semi’s was either partially in the ditch or on the shoulder when it was struck by the second semi. One driver got out, the other driver was still inside his cab.

No other details are currently available. Check back for updates.

A reminder for Atlantic residents: Atlantic Police in coordination with the Atlantic Fire Department, Cass County Sheriff’s Office, Cass County Emergency Management Agency, Atlantic Medivac, and the Iowa State Patrol, will be conducting an “Active Intruder” drill today at the Atlantic High School. Officials stress that “There are currently no known threats of violence to any schools or facilities within the area. This is strictly A DRILL.

The drill will begin shortly after 10-a.m., and will include and “ALERT” from the principal’s office, notifying everyone in the building of the “Danger Zone.” Those area affected in the “Danger Zone,” will be practicing “Lockdown/Barricade,” and discussing alternate exits from the classroom.

The principal will continue to “Inform” everyone of any changes to the “Danger Zone.” “Counter,” which was taught in previous lessons, will not be practiced in the first drill. Classrooms not in the “Danger Zone,” will practice the preferred response, “Evacuation.”

To ensure participant safety, certain intersections and roads surrounding the Atlantic High School, specifically the area of E. 14th Street, will be temporarily blocked-off and inaccessible. The closures include: Eastbound traffic on 14th Street from Olive Street; 14th and Roosevelt Streets; 14th and Lincoln Streets; 14th and Mulberry; 14th and Cherry; 14th and Plum, and westbound traffic on 14th Street from Redwood Drive.
