Harvey drenches Louisiana, sparks blast at Texas chemical plant

Louisiana/Texas: The remnants of tropical storm Harvey drenched northern Louisiana on Thursday as it moved inland, leaving behind record flooding that paralysed the US energy hub of Houston, killed at least 35 people and drove tens of thousands from their homes.

Two explosions were reported at a flood-hit chemical plant in Crosby, Texas, 30 miles (48kms) northeast of Houston, with one sheriff’s deputy sent to the hospital after inhaling toxic chemicals.

The Arkema SA plant, which local media said was flooded and accessible only by boat, had lost power as a result of the storm, causing organic peroxides stored there to warm to dangerous levels. When the chemicals exploded, toxic gas and smoke were released.

A 1.5-mile (2.4kms) radius around the plant had been evacuated and the company urged people to stay away from the area, warning further blasts were likely.

“The question is whether or not we can actually get in and assess the full scale of the impact from an environmental standpoint to an infrastructure standpoint,” Federal Emergency Management Agency (FEMA) administrator Brock Long said at a news briefing. “The plume is incredibly dangerous.”

The storm’s death toll was rising as bodies were found in receding waters. Some 32,000 people were forced into shelters around the region since Harvey came ashore on Friday near Rockport, Texas, as the most powerful hurricane to hit the state in a half-century.

By Thursday, the storm was downgraded to a tropical depression, located about 15 miles (24kms) south of Monroe, Louisiana. The storm’s rains wrought the most damage along the Gulf Coast and the National Weather Service warned that as much as 10 inches (25.4cms) could fall in parts of Mississippi, Tennessee and Kentucky.

Potential for more flooding

Rivers and reservoirs in Texas and Louisiana remained at or near flood level, with officials warning that high water would remain a danger in the region for the next few days.

Federal officials also had already rescued 10,000 people form flooded homes and would continue to search, Brock said.

The Houston Fire Department will begin a block-by-block effort on Thursday to rescue stranded survivors and recover bodies, assistant fire chief Richard Mann told reporters. Large numbers of civilian volunteers also joined in the rescue effort.

Nine members of the ad-hoc “Cajun Navy” towing boats behind pickup trucks gathered in Lake Charles early on Thursday, deliberating whether they could safely get in to the parts of coastal southeastern Texas, including Orange, Port Arthur and Beaumont, badly flooded by the storm.

“You can’t get anywhere by vehicle,” said Troy Payne, 56, who had driven in from Atlanta. “To me, this is a helicopter function from here on out unless the water level falls.”

Payne said he planned to drive north to try to find another way into Texas.

Nearly 30 inches (76.2 cm) of rain hit the Port Arthur area, the National Weather Service said.

Beaumont said it had lost its water supply due to flood damage to its main pumping station. Residents in the city of about 120,000 people would lose water pressure from Thursday morning.

Fort Bend County ordered a mandatory evacuation on Thursday for areas near the Barker Reservoir, which was threatening to flood. The reservoir is about 20 miles (32kms) west of Houston.

Clear skies in Houston on Wednesday brought relief to the energy hub and fourth-largest US city after five days of catastrophic downpours. The first flight out of Houston since the storm hit boarded on Wednesday evening.

Police in Houston’s Harris County said 17 people remained missing.

Some 325,000 people and businesses already had applied for FEMA assistance and the agency already has paid out $57 million in aid, Brock said.

Energy production disrupted

Flooding shut the nation’s largest oil refinery in Port Arthur in the latest hit to US energy infrastructure that has sent gasoline prices climbing and disrupted global fuel supplies.

The storm prompted the US Energy Department to authorize the first emergency release of crude oil from the Strategic Petroleum Reserve since 2012. Some 500,000 barrels of oil will be delivered to a Phillips 66 refinery in Louisiana unaffected by the storm, an Energy Department spokeswoman said in a statement.

Average US retail gasoline prices have surged to $2.449 per gallon nationwide in the storm’s wake, up 10.1 cents from a week ago, the AAA said on Thursday.

Moody’s Analytics is estimating the economic cost from Harvey for southeast Texas at $51 billion to $75 billion, ranking it among the costliest storms in US history.

At least $23 billion worth of property has been affected by flooding from Harvey just in parts of Texas’ Harris and Galveston counties, a Reuters analysis of satellite imagery and property data showed.

Governor Greg Abbott warned that floodwaters would linger for up to a week. The area affected is larger than that hit by 2005’s Hurricane Katrina, which killed more than 1,800 people in New Orleans, and 2012’s Superstorm Sandy, which killed 132 around New York and New Jersey, he said.

US vice president Mike Pence and several cabinet secretaries will travel to Texas on Thursday to meet residents affected by the storm. Reuters
