Following the life-threatening Hurricane Harvey that struck Texas, thousands of people who are currently trapped on their rooftops in Houston, are pleading for help on social media.

According to reports, the storm swept into Texas as a Category 4 hurricane over the weekend, but continued its relentless devastation in Houston on Sunday as the catastrophic flooding forced evacuations.

Many trapped residents are pleading on social media for help, as the Houston police department have urged the public to donate their boats in other to rescue victims after they received 6,000 calls for rescues. 

The storm has claimed the lives at least five people while the Galveston County alone estimates that up to 1,200 people had to be rescued so far.

Mail Online also reports that the storm has already dumped a historic 11 trillion gallons of water on Texas with another 27 inches of rain falling so far and another 23 inches expected to come within the next few days. 

FEMA, the Federal Emergency Management Agency, revealed it would take the area years to recover from the storm which is the worst this decade.
