As Harvey continues to dump heavy rainfall over Texas, southwestern Louisiana now faces a threat of flooding from the slow-moving storm.
The former Category 4 hurricane has battered the Texas coast with destructive winds and drenching downpours following landfall on Aug. 25. Widespread and unprecedented flooding is ongoing in the Houston, Texas, area, with thousands of water rescues completed and tens of thousands of 911 calls placed.
In addition to the devastating flooding in southern Texas, there have also been widespread power outages, isolated tornadoes and at least nine reported deaths as of Monday afternoon.
Harvey is the first major hurricane to impact the United States since Wilma in 2005.

The damage could cause chemicals to be released into the air, but Exxon expects air emissions linked to the damage to end by Friday, CNN reported.

3:25 p.m. CDT Monday: Officials are preparing to evacuate the 350 patients at Houston’s Ben Taub Hospital hospital and transport them to other area hospitals.
Flooding from Harvey has already made its way into the hospital’s basement and is threatening the supply of medicine and food, the Associated Press said.
The Ben Taub Hospital is located near the Brays Bayou which was in major flood stage over the weekend.
Heavy rain continues to fall across the Houston area and is contributing to additional flooding.
2:20 p.m. CDT Monday: Floodwaters from Harvey swept away a van carrying six people in Houston with the occupants feared to be dead. This brings the death toll from the storm up to eight.
Authorities are expecting this number to rise in the coming days as rescue efforts continue.

11:21 a.m. CDT Monday: Texas Gov. Greg Abbott has activated the entire Texas National Guard to assist with Harvey relief efforts.
It is imperative that we do everything possible to protect the lives and safety of people across the state of Texas as we continue to face the aftermath of this storm,” said Abbott. “The Texas National Guard is working closely with FEMA and federal troops to respond urgently to the growing needs of Texans who have fallen victim to Hurricane Harvey, and the activation of the entire Guard will assist in the efforts already underway. I would like to thank FEMA Administrator Brock Long, as well as all our brave first responders for their hard work in helping those impacted by this terrible storm.”
"While this is still a dangerous situation with a long response effort ahead, the state and people of Texas are resilient," said Long. "FEMA was here before the storm hit, and we will be here as long as needed, actively coordinating the full resources of the federal government, to support Gov. Abbott and the state."
11:02 a.m. CDT Monday: Harvey’s heavy rainfall has inundated two Houston dams. The U.S. Army Corps of Engineers is releasing water from those dams to alleviate the high water levels.
The reservoirs' water levels were increasing by more than half a foot per hour by Monday morning, according to Galveston District Commander Col. Lars Zetterstrom.
“If we don’t begin releasing now, the volume of uncontrolled water around the dams will be higher and have a greater impact on the surrounding communities,” Zetterstrom said in a statement.
The district is coordinating floodwater releases from Addicks and Barker reservoirs with the Harris County Control District.
Zetterstrom urged residents living near the reservoirs to “be vigilant,” as waters are rising rapidly.
10:53 a.m. CDT Monday: Among all weather-related natural disasters, floods have been both the most common and most costly in the United States, according to the U.S. Geological Survey. They can create billions of dollars in damage a year and kill hundreds of people.
Houston police have completed over 2,000 water rescues with another 185 requests for help still pending, officials said in a press conference.
The Harris County Sheriff’s Office has asked residents awaiting rescue to identify themselves by handing a towel or sheet prominently. Officials are also warning against looting as the flooding situation unfolds.
7:57 a.m. CDT Monday: August 2017 is now Houston's wettest month on record, according to the National Weather Service. Harvey drenched the city with 16.07 inches of rain on Sunday, which is the single highest daily rainfall total in Houston's history.
7:33 a.m. CDT Monday: The National Weather Service forecast shows that the Brazos River in Fort Bend County, Texas, will likely crest sometime on Tuesday at an elevation of 59 feet due to rapidly rising flood waters.
Cresting is the highest stage or level of a flood wave as it passes a certain point.
“A flood of this magnitude is an 800-year event and it exceeds the design specifications of our levees,” said County Judge Robert Hebert.
The 59-foot river level is threatening to over top many levees in the area. Judge Hebert has ordered both voluntary and mandatory evacuations for areas along the river, according to the Fort Bend County Office of Emergency Management.
