DELPHI, Ind. – Thunderstorms and snowstorms spread across the eastern half of the nation Tuesday, making travel miserable for voters in states holding primaries and causing flooding that chased some people from their homes in Indiana.

It was the second evacuation in less than a month for some Indiana residents.

Snow spread out of Colorado on a path across the central Plains and was likely to reach the upper Great Lakes by nightfall. Up to 11 inches of snow was possible in parts of Wisconsin.

In warmer air, a band of rain and thunderstorms extended from Oklahoma up the Ohio Valley to New York state.

Snow or rain fell during the morning in parts of Super Tuesday states Arkansas, Colorado, Connecticut, Illinois, Kansas, Massachusetts, Missouri, New Jersey, New York and Oklahoma.

That band of stormy weather was headed toward the Southeast, with a threat of damaging wind, hail and a chance of tornadoes in places, worrying Tennessee’s election coordinator.

“You never know what type of weather issue you may have,” said Brook Thompson.

It could be much worse. Voters heading to party caucuses in Alaska faced lows of 50 degrees below zero, with more than a foot of new snow in Juneau, the state’s capital.

Officials in two northwest Indiana counties urged people who live along the Tippecanoe River to evacuate Tuesday after heavy rain fell during the night.

“Early this morning Carroll County Sheriff’s deputies began driving up and down the roads waking people up with sirens and public address announcements,” said Carroll County Emergency Management director Dave McDowell.

McDowell said many people were still out of the area because of January flooding that killed three people and caused more than $33 million damage. Others had returned but were leaving again.

Residents were urged to leave homes downstream from Carroll County’s Oakdale Dam, where flood gates were opened early Tuesday to release rising water. One of those residents, Donna Marshall, said she had nightmares after seeing warnings on television Monday night.

“I didn’t realize how much the last one affected me. I kept thinking we were going to get swept off,” Marshall said.

High water closed roads in other parts of northern Indiana and flood warnings and watches were in effect for much of the state.

Elsewhere, New Mexico Gov. Bill Richardson on Tuesday ordered more than a dozen National Guard troops to the mountain town of Chama, saying deep snow has blocked roads, damaged buildings and stranded residents in their homes

More than 33 inches of snow has fallen since Saturday at Chama, sitting at an elevation of 7,800 feet, the National Weather Service said.
