Virginia Gov. Ralph Northam (D) declared a state of emergency Friday in advance of Hurricane Isaias, which he said could affect coastal parts of the state as soon as this weekend.

He said the declaration ensures that local jurisdictions would have the help needed to protect residents.

A state of emergency lets Virginia mobilize resources and equipment needed for response and recovery efforts, the governor’s office said.

The storm’s track remained uncertain, the office said in a statement, but “it appears increasingly likely” that Virginia could see some impact. That made it necessary, the statement said, to prepare for possible flooding, high winds and storm surge.

The statement encouraged residents to consult Virginia’s hurricane evacuation guide during the pandemic, which outlines preparedness, response, and recovery actions designed to reduce the risk of transmission of the virus and protect public health.
