Hurricane Ida crashed into the Louisiana coast as an extremely dangerous Category 4 storm on Sunday, the 16th anniversary of Katrina, cutting power for millions and temporarily reversing the flow of the Mississippi River. So far, Ida has caused “catastrophic” wind damage, as well as a life-threatening storm surge, flooding, and heavy rainfall, according to the National Hurricane Center. The full order of damage became apparent on Monday when dawn broke over a blacked-out region. Meanwhile, the Biden administration has declared a presidential major disaster declaration to free up resources for rescue and recovery. Below are updates about Ida’s path and impact.
