At least 11 deaths are now being blamed on a massive storm system that's battered the several parts of the country.

Authorities said a 101-year-old man died in a fire sparked by lightning in Shreveport, Louisiana.

At least ten others have died on the Texas-Mexico border where a tornado hit near Eagle Pass, Texas.

Five of the ten people killed by the tornado were from the same family in Texas. They were found huddled together in a mobile home that was slammed into a school building. At least three people died across the border from Eagle Pass.

Teams are still assessing the damage.

The tornado hit an area called Rosita Valley, and reports said that at least 40 people were injured. At least three more people were killed on the Mexico side of the border.

The mayor of Eagle Pass, Chad "Chuck" Foster, said an elementary school was heavily damaged and possibly destroyed.

University Hospital in San Antonio said at least two people were being transported from Eagle Pass -- both children, KSAT-TV reported.

Foster said the twister destroyed more than 20 homes, an elementary school and a municipal sewer treatment plant. No one was in the school because the storm hit in the evening.

A local hospital said it treated 74 patients, including four who are reported in critical condition.

The tornado was spawned by the same storm system that dumped heavy snow in Colorado and torrential rain in Nebraska and Iowa.

The International Bridge in Eagle Pass also sustained damage. There were also reports of heavy damage in Piedras Negras, which is the Mexican town over the Rio Grande opposite Eagle Pass.

A command center was set up at Eagle Pass City Hall and was manned by the Eagle Pass Police Department, Maverick County Sheriff's Office and the U.S. Border Patrol.

The American Red Cross also set up an emergency shelter in Eagle Pass at the Eagle Pass Multipurpose Center.

There was no word on how many people needed to take shelter.

Boulder Snarls Colorado Traffic

Southbound Highway 285 was closed after a 50-ton boulder fell on the road at about 2 p.m. Tuesday. The road reopened just before 11 p.m.

The boulder -- which is 12 feet by 12 feet by 10 feet -- sat on two southbound lanes so southbound Highway 285 was closed at milepost 246.7, near Parmalee Gulch, the Colorado Department of Transportation said. Northbound traffic was allowed through the area but was limited to one lane.

The boulder was so large that CDOT equipment could not move it from the highway so crews had to blast the boulder into more manageable chunks. Workers drilled a hole in the middle of the boulder, stuck dynamite in it and then blew it into pieces that were then bulldozed out of the way.

During the blasting and cleanup, all northbound and southbound lanes were closed.

Fortunately, no one was caught or hurt by the tumbling boulder. Wet weather loosened the massive rock from the hillside and caused it to roll down to the road, CDOT said.

A trucker from Kentucky said he heard the loud rumbling of a freight train before he saw the boulder tumble down and crash onto the road -- about a car's length in front of him.

"It slammed there right on the street -- dead in front of me," said trucker Steven Jones.

Jones said it's his lucky day and said he planned to buy a lottery ticket later.

The incident backed up traffic for 1.5 miles, and it took almost two hours to clear because cars were redirected on to Highway 8.

Elsewhere in Colorado, slick pavement, accidents, a fallen power line and poor visibility forced almost a dozen road closures. Hail the size of quarters pelted parts of southeastern Colorado. And authorities say some rural roads have been blocked by flooding in the northeast part of the state, as well as in Kansas and Nebraska.

Rain, snow and fog greeted Wednesday morning commuters following Tuesday’s big spring storm that dropped up to 2 feet of snow and 2 inches of water on parts of Colorado.

Roads were icy in the Colorado high country Wednesday morning, and a number of rollover accidents were reported on Interstate 70 west of Denver. Blowing snow was limited visibility in some areas.

Fog developed in sections of the foothills west of Denver early Wednesday morning, cutting visibility to just 1/4 mile.

A number of schools and school districts were closed Wednesday, but KMGH-TV in Denver reported that temperatures could hit 80 degrees by Sunday.

The system has left Colorado with more than a foot of snow. Forecasters said parts of Nebraska may get up to 7 inches of rain before the storm is finished.

Oklahoma Hit Hard

Strong to severe storms rolled through central Oklahoma on Tuesday, according to KOCO-TV.

Some areas across central and eastern Oklahoma received up to an inch of rain, and many areas got some hail. A tornado warning was issued for Osage County by mid-afternoon, but there was no official reports of twisters in the state.

Skies are to become partly sunny Wednesday, but with a continuing chance for scattered showers or thunderstorms and highs from the mid-60s to the mid-70s.

Clouds are to return Thursday with another chance for scattered rainfall and highs again from the mid-60s to the mid-70s.
