Days after Hurricane Ida struck Louisiana, a heat advisory and flood watch have been issued in parts of the state from noon through the evening Monday (Sept. 6). As multiple news outlets reported, residents in New Orleans, Baton Rouge and other parts of southeastern Louisiana are being advised to prepare for a temperature high of 90 degrees, an expected heat index of 100 to 105 degrees and two to four inches of heavy rain.

The precipitation, according to the National Weather Service, may potentially result in flooding since soil in the region was already saturated with water from the category four hurricane.

Therefore, Louisiana residents have also been urged to move to higher ground, pay attention to flood dangers at night and prevent from driving into floodwaters. “Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the NWS added.

According to USA Today, Hurricane Ida swamped Louisiana last week, killing 13 people in the state and leaving millions without power. As of Monday, more than half a million people remain without power, which may be restored in most homes by Wednesday (Sept. 8). Individuals and families in heavily-impacted areas, however, may have to wait until the month’s end as recovery efforts have reportedly become more difficult to carry out considering the lack of power, excess heat, a shortage of fuel and water issues in the state.

As for those in New York and New Jersey, more than 50 people have reportedly passed away from extreme flooding caused by the remnants of Hurricane Ida. As a result, President Joe Biden has issued a major disaster declaration, allowing for the states to receive federal assistance.

As USA Today reported, Hurricane Ida is reportedly the deadliest hurricane to hit the U.S., specifically the northeastern area, in four years.
