In a widely-circulated video over the weekend, a Texas couple was rescued from their flooded home by boaters in the aftermath of Hurricane Harvey.

The storm, which dropped from a category 4 hurricane on Friday to a tropical storm by Monday, deposited more than 30 inches of rain in some Texas counties. Texans are still expecting the flood surge to worsen over the next few days, as tropical storm Harvey planted itself over the state on Monday and was moving slowly toward Louisiana.

CNN correspondent Ed Lavandera and producer Jason Morris helped volunteer Austin Seth rescue an elderly couple and their dogs from their flooded home in Dickinson, Texas. The clip shows both residents in waist-deep water being rescued from the doorway of their house. One of the people rescued was reported to be afflicted with Alzheimer’s disease.

Prior to the storm hitting last week, home health care agencies in affected regions braced for the storm’s wrath and implemented their emergency protocols. The home health industry is also readying itself for new emergency preparation requirements set to go into effect in November.

The flooding in the Houston area reached “unprecedented” levels over the weekend after the area experienced multiple days of torrential downpour from the storm that claimed at least two lives, according to the National Weather Service (NWS). NWS also stated that the impacts of the storm were unknown, as some areas could see as much as 50 inches of rain in total.

The CNN clip, which gained national attention, is just one of hundreds of rescue scenarios in the affected areas in Texas. Another viral image from the weekend showed a group of assisted living residents in several feet of water inside La Vita Bella, an assisted living facility in Dickinson. The facility’s owners posted the heart-wrenching images to social media to plead for emergency services. The seniors were rescued by first responders and air lifted to safety on Sunday afternoon, Galveston Daily News reported.

President Donald Trump declared a state of emergency in Texas and Louisiana.The Department of Health and Human Services Secretary Tom Price declared a public health emergency in the state over the weekend.

“HHS is taking the necessary measures and has mobilized the resources to provide immediate assistance to those affected by Hurricane Harvey,” Secretary Price said in a statement. “We recognize the gravity of the situation in Texas, and the declaration of a public health emergency will provide additional flexibility and authority to help those who have been impacted by the storm.”
