Ida weakens to tropical storm after knocking out power to New Orleans

Hurricane Ida weakened to a tropical storm Monday after slamming into coastal Louisiana as one of the strongest storms to make landfall in the region, cutting off power to more than 1 million homes and businesses, including the entire city of New Orleans.

The powerful weather system continued to pose a danger for multiple states as it swept inland, and was expected to trigger major search and rescue operations. But the missions are getting complicated by inoperable 911 lines reported throughout southeastern Louisiana, including the heavily populated Orleans and Jefferson parishes.
