BATON ROUGE (AP) — President Donald Trump on Monday issued a federal emergency declaration for Louisiana as heavy rains from Harvey ratcheted up fears of destructive flooding.
Tornado and flash flood watches covered parts of southwest Louisiana as Harvey dropped torrential rains on that part of the state.
Trump's emergency declaration initially covers five parishes in southwest Louisiana: Beauregard, Calcasieu, Cameron, Jefferson Davis and Vermillion. More areas can be added later.
A White House statement says the action authorizes the Federal Emergency Management Agency to coordinate disaster relief efforts. The declaration also authorizes the federal government to cover 75 percent of costs of certain emergency protective measures.
Louisiana Gov. John Bel Edwards requested the declaration in a letter to the White House on Sunday.
"Significant lifesaving efforts such as search and rescue, transportation to shelters, logistical support, and shelter operations will be particularly needed in parts of southwest Louisiana and can be supported by the federal government with an emergency declaration," the governor wrote.
The efforts will be especially needed in southwest Louisiana, where 10 inches (25 centimeters) to 20 inches (50 centimeters) of rain could fall, the governor added.
"We know that the predicted rainfall from Hurricane Harvey will produce dangerous flooding across our state, including some of the same areas affected by the 2016 floods," Edwards wrote.
Harvey, the most fearsome hurricane to hit the U.S. in more than a decade, came ashore late Friday about 30 miles (48 kilometers) northeast of Corpus Christi, Texas, as a Category 4 storm. The slow-moving storm has caused catastrophic flooding in Texas.
As dawn broke Monday in Louisiana, The National Weather Service radar for the Lake Charles area was lit up in orange and red where heavy rains from one of Harvey's outer bands streamed from the Gulf of Mexico onto the Louisiana coast.
"With the conveyer belt of moisture continuing northward, additional area rainfall amounts of 10 to 15 inches (25 to 38 centimeters) is expected across southeast Texas and southwest Louisiana, with 5 to 10 inches (12 to 25 centimeters) expected across Central and South Central Louisiana through Thursday afternoon," forecasters said in a Monday morning update.
Tornadoes also could threaten southwest Louisiana, which was under a tornado watch Monday. Tornadoes could threaten the region through Monday evening, according to the weather service's Storm Prediction Center.
*****
Massive flooding caused by Harvey along Texas' refinery-rich coast could have long-standing and far-reaching consequences for the state's oil and gas industry and the larger U.S. economy. The storm's remnants left much of Houston underwater on Sunday, and the National Weather Service says it's not over yet: Some parts of Houston and its suburbs could end up with as much as 50 inches (1.3 meters) of rain.
With the heavy precipitation expected to last for days, it's still unclear how bad the damage will be, but there is already evidence of widespread losses. Key oil and gas facilities along the Texas Gulf Coast have temporarily shut down, and flooding in the Houston and Beaumont areas could seriously pinch gasoline supplies. Companies operating in the Gulf of Mexico have evacuated drilling platforms and rigs, crimping the flow of oil and gas.
Experts believe gasoline prices could increase as much as 25 cents a gallon.
Harvey's toll on air travel in the U.S. is set to extend into Monday, with the tracking service FlightAware.com reporting that more than 1,400 flights already have been canceled. That's in addition to more than 2,000 canceled over the weekend.
Economy watchers were looking to oil futures markets Sunday night and stock trading in the U.S. Monday morning for further indications of fallout.
Here's what was known as of Sunday night:
REFINERIES
Nearly a third of U.S. refining capacity sits in low-lying areas along the coast from Corpus Christi, Texas, to Lake Charles, Louisiana. Beyond the shutdown of refineries at risk of a direct strike from high winds, there's the threat of flooding and potential power outages for gasoline supplies.
Refinery outages continued to spread Sunday, with about 2.2 million barrels per day of refining capacity down or being brought down, according to analysts at S&P Global.
Valero Energy Corp., whose two big Corpus Christi refineries escaped damage, said it was working with federal and Texas agencies and its business partners to determine what infrastructure was needed to resume refinery operations.
Even before Harvey hit, the prospect of supply disruptions sent gasoline futures to $1.74 a gallon, their highest level since April, before they retreated to around $1.67 by Friday afternoon. At the pump, experts see gasoline increasing 10 cents to 25 cents a gallon.
Given the strictures faced by the refineries, "This is the dominoes starting to fall," Patrick DeHaan, senior petroleum analyst for Gas Buddy, said Sunday. "This is sort of slowly turning out to be the worst-case scenario."
OIL AND GAS
Companies have evacuated workers from oil platforms in the Gulf of Mexico. The U.S. Bureau of Safety and Environmental Enforcement said Sunday that workers had been removed from 105 of the 737 manned platforms used to pump oil and gas from beneath the Gulf.
The agency estimated that platforms accounting for about 22 percent of oil production and 26 percent of natural gas output in the Gulf had been shut down.
"After the storm has passed, facilities will be inspected," the agency said in a news release. "Once all standard checks have been completed, production from undamaged facilities will be brought back on line immediately. Facilities sustaining damage may take longer to bring back on line."
SHIPPING
The shipping industry also is expected to be disrupted by the worst hurricane to hit the Texas coast in more than 50 years. Shipping terminals along the Texas coast shut down as the storm approached. Port operations in Corpus Christi and Galveston closed, and the port of Houston said container terminals and general cargo facilities closed around midday Friday.
Rates increased for carrying freight between the Gulf and the U.S. East Coast.
TRAVEL
More than 1,400 flight cancellations are reported for Monday, according to FlightAware.
Houston's two airports were closed to all flights except those connected to relief efforts. Houston Bush Intercontinental Airport was not expected to reopen Monday until noon at the earliest. Houston International Airport was scheduled to remain closed until Wednesday morning.
Airlines were offering customers the chance to reschedule trips that would take them to Houston, San Antonio or Austin from Friday through the weekend.
UTILITIES
Researchers at Texas A&M University estimated that the storm would knock out power for at least 1.25 million people in Texas. They said the hardest-hit areas will include Corpus Christi, which is on the coast, and San Antonio, which is about 140 miles (225 kilometers) inland.
INSURANCE
A firm that does forecasts for insurance companies expects wind-damage claims in the low billions of dollars, and possibly reaching as high as $6 billion.
Risk Management Solutions Inc. said storm surges and inland flooding could be an even bigger source of losses. If the firm is correct, that would put homeowners and the government-backed National Flood Insurance Program at risk.
The flood program is run by the Federal Emergency Management Agency, which owes the Treasury about $23 billion in funds borrowed to cover the cost of past disasters, according to a recent report by the U.S. Government Accountability Office.
Homeowner policies offered by insurance companies typically don't cover flood damage, yet a relatively small percentage of homeowners have flood insurance through the federal program.
Property data firm CoreLogic estimated that insured losses for home and commercial properties, as of Friday, would be $1 billion to $2 billion from wind and storm- surge damage.
