Moody’s Analytics estimated the economic cost from Harvey for southeastern Texas at $51 billion to $75 billion, ranking it among the costliest storms in American history.
The event has drawn comparisons with Hurricane Katrina, which killed more than 1,800 people in New Orleans in 2005. Then-President George W. Bush’s administration was criticized for its haphazard initial response to that storm, and Donald Trump’s administration was taking care to be seen as responding quickly to its first major natural disaster.
Trump was to return to the region on Saturday. Early Thursday, explosions could be heard at a chemical plant in Crosby, Texas, owned by Arkema SA. Refrigeration systems failed in a truck
storing volatile chemicals, which ignited as they warmed, sending smoke plumes 40-feet (12-meters) into the air, according to company and public safety officials.
Public safety officials insisted there was no risk to the public outside a 1.5-mile (2.4-km) safety perimeter, but more fires were expected at the facility, underscoring worries of possible damage at other petrochemical plants and oil refineries that dot the region.
As signs of normal life returned to Houston, the nation’s fourth most populous city, there were also concerns about health risks from bacteria and pollutants in floodwater.
