(Reuters) – More than 189,000 homes and businesses in the central and southern US were without power late on Monday, data from PowerOutage.us showed, after a winter storm brought snow, ice and ice temperature.

The US is bracing for more disruption as blizzard conditions continue in many states.

The National Weather Service said the storm is expected to move offshore late Monday to be replaced by Arctic air, lowering temperatures during the day.

The governors of several states, including Kansas, Kentucky, Arkansas, West Virginia and Virginia, have declared states of emergency.

The Electric Reliability Council of Texas (ERCOT) on Sunday announced a weather watch from January 6-10, saying that expected cold weather across its region will increase demand for electricity and reduce reserves.

However, it said grid operations are expected to remain normal during the weather watch.

Transmission organization PJM Interconnection has issued a cold weather advisory for the Western Region, which includes parts of Kentucky, Ohio and Pennsylvania, for January 8-10.

The advisory will help power producers prepare for severe weather and ensure reliable power supply during periods of high demand.

Appalachian Power Company reported the highest number of affected customers, with 43,850 without power in Virginia and 28,525 in West Virginia.

CenterPoint Energy (NYSE: ) Indiana said 33,364 customers reported power outages in Indiana.
