HOUSTON (ICIS)--Hurricane Nicholas largely spared US Gulf coast refineries and chemical plants after making landfall on Monday night as a category 1 storm. But the remnants could generate heavy rainfall over Louisiana, which is still recovering from Hurricane Ida.
Meteorologists at the National Hurricane Center (NHC) said significant rainfall amounts are expected from the upper coast of Texas, across Louisiana and the southern parts of Mississippi and Alabama.
As of late Tuesday afternoon, the system, which has been downgraded to a tropical storm, was 50 miles (80km) east of Houston and is moving slowly to the east-northeast at about 6 miles/hour.
The NHC said maximum sustained winds are still near 40 miles/hour.
The biggest concern moving forward is likely to be from rainfall, which can lead to closed roads and rail disruptions.
Refineries and chemical plants in the US Gulf appeared to have sustained minimal damage from the storm.
ExxonMobil said its Texas refineries and chemical complexes in Baytown and Beaumont are operating as normal and that there was no significant damage or flooding at the sites.
Shell conducted a thorough post-storm damage assessment at its complex in Deer Park, Texas, and was running normally as of mid-afternoon on Tuesday.
