Isaias weakens to a post-tropical storm after killing four. About 670,000 customers are without power in four states
CBS News and NBC News reported at least four deaths from Hurricane Isaias, which came ashore near Destin, Florida, on Friday night as a Category 2 hurricane and weakened within hours to a post-tropical cyclone. A wire report carried by GMA News, citing local authorities and electricity-monitoring services, said about 670,000 customers were without power in Florida, Alabama, Georgia and Mississippi. A local station, WVTM, reported a tree falling on a Birmingham, Alabama, home and killing one person. The New York Times said towns near landfall were relieved that damage was not worse, with fallen trees and power cuts instead of catastrophic flooding, and that flash floods now threaten parts of the Southeast. NBC reported millions still under threat of torrential rain, flooding and tornadoes. Bloomberg Intelligence’s insurance analyst told Bloomberg Television that insured losses could reach the single-digit billions of dollars. Bloomberg reported on Friday that nearly three-quarters of Gulf of Mexico oil output was shut in.
The wind has eased but the rain has not, and flash floods and downed power lines are what hurt people after a hurricane weakens. The storm also hit a fuel market that is already tight, with diesel near a record, so a slow restart of Gulf production would be felt at the pump.
In Florida, Alabama, Georgia and Mississippi, stay off flooded roads, treat downed lines as live and check your utility’s outage map. Elsewhere, expect oil and fuel futures to react first when trading reopens Sunday evening, and pump prices to follow if shut-ins last.
Weakening before landfall and Florida’s stronger building codes kept damage below the early fears, as the Times and Bloomberg Intelligence described.
A lower death toll is not the same as little harm. Inland flooding is still arriving, 670,000 customers have no power, and the oil restart is unscheduled.
Do not treat the storm as over because the winds eased. On Sunday, watch rainfall and river levels, the pace of power restoration, any additional confirmed deaths and the first insurer and state damage counts. The oil number to watch is how many shut-in platforms get the all-clear. Ignore unsourced maps.
