Hurricane Ida – Update 36

Updated 9/22/2021 at 2:00 p.m. CDT – Updates in bold

Hurricane Ida made landfall near Port Fourchon, LA around 11:55 a.m. CDT on Sunday, Aug 29 as an “extremely dangerous” Category 4 storm with maximum sustained winds of 150 mph, which is very close to a Category 5 hurricane, and a minimum central pressure of 930 mb, according to the National Weather Service (NWS) National Hurricane Center (NHC).

The storm maintained major category strength as it made its way over most of the petrochemical industry in southeastern Louisiana. At approximately 9 p.m. CDT on Sunday, Aug 29, an estimated nine hours after making landfall, Hurricane Ida weakened to a Category 2 hurricane with its eye just north of Garyville, LA, according to NWS. By 11 p.m. CDT, Hurricane Ida had decreased to a Category 1 hurricane near Maurepas, LA.

Louisiana produces nearly 25 billion pounds of ethylene each year (29% of US capacity). Based on the path of Hurricane Ida, it is estimated that 61.5% Louisiana’s ethylene capacity was offline immediately after the storm’s landfall, representing approximately 18% of total US capacity. For a list of current ethylene capacity that is offline by facility, please see page 7 of the OPIS PCW Daily Wire report.

Downstream, the storm affected roughly 14% of North American PE capacity, 11% of North American PP capacity and 25% of North American PS capacity. Approximately 40% of US PVC production was down. Hurricane Ida impacted 44% of the US styrene capacity (37% of North American capacity).
