SHREVEPORT, La. (AP) - Freezing rain and sleet closed Grambling State University early, canceled flights, sent drivers skidding and broke power lines in north Louisiana.
Police in both Shreveport and Monroe closed ramps onto Interstate 20.
Grambling sent students home at noon Tuesday but Louisiana Tech stayed open. Northwestern State canceled evening classes but said it would open Wednesday. Ouachita, Richland, East Carroll, Madison, Union, West Carroll, Morehouse parishes and Monroe city schools were closed Tuesday.
Entergy reports nearly 6,900 Louisiana customers without power Tuesday afternoon - 6,000 in Ouachita Parish, nearly 590 in East Carroll Parish and the rest around central and north Louisiana.
Entergy spokesman Roderick Worthy said some early outages were from vehicle accidents that damaged utility poles.
