LA PORTE, Texas — Brisk winds out of the north to northeast put communities near industrial areas in east Harris County at risk of more volatile chemicals in the air, according to the county's emergency management office.

The county says all of its readings as of 3:50 p.m. Sunday had "been below levels that would warrant protective actions to be taken." But the winds could cause short-lived spikes, the county says.

Meanwhile, La Porte chemical plant Nouryon Battleground had issued a shelter in place as of 1:40 p.m. for a chemical release at Intercontinental Terminals Company, where storage tanks burned on and off for about a week earlier this month.

That advisory has since been lifted.

The county's public health department still says based on air monitoring reports, "there is a low health risk for the community."
