When Hurricane Harvey hit landfall Friday it brought along heavy rains which led to flooding in most of southeast Texas. And one of the most devastated areas to succumb to flooding was Houston. 

On Saturday, nearly 20 inches of water fell in 24 hours crippling the city with 10 more inches expected to fall. 

“This is a life-threatening situation,” said Michael Palmer, lead meteorologist at the Weather Channel.

Houston city officials told residents to shelter in place and to not call 911 unless there was imminent danger because emergency services were at capacity. "If you are in a flooding situation, stay calm, do not panic," the Coast Guard said in a statement. "Do not go into the attic, rescuers from the air cannot see you."  

Others took heed to the warning and fled to their rooftops to be rescued by helicopter responders. Authorities also told victims to not go to their attics unless they had axes. 

"When you get rates of over six inches of rainfall an hour it overflows, the drainage systems and homes and businesses will be flooded, which is what we're seeing now in Houston," Palmer said.

According to The Washington Post, 1,000 water rescues have taken place as nearly 30 inches of rainfall has left the city in ruins. Estimates indicate that at least five people have died from the damage made by Hurricane Harvey. 

In wake of the chaos, Twitter has become a resource for those to keep in touch with family and provide updates on the flooding firsthand. 

A few users have said that flood waters are starting to let up.

The floodwaters from Harvey has made traveling on roads impossible. USA Today reports that roads have alligators and swarms of fire ants in them. 

Harvey became a Category 4 by Saturday and wreaked havoc on the oil refineries in its path, possibly causing a spike in gas prices over the next month.
