State government offices in Denver and surrounding suburbs – as well as Denver city and county government offices – will be closed Wednesday ahead of a powerful storm that’s prompted a blizzard warning in the Rocky Mountains.

“Anticipated extreme weather” has closed state offices in the Denver metro, according to a Wednesday press release from Gov. Jared Polis’ office.

Essential personnel must report to work on time, and essential facilities will maintain regular schedules, according to the release.

The House has a snow day Wednesday, according to a Tuesday evening retweet by Colorado House Democrats. The Colorado General Assembly website still lists an agenda for both chambers, however, as of 9:15 a.m.

The state Senate is in session Wednesday, according to Colorado Politics’ Conrad Swanson.

Denver county courts, all Denver libraries, the Denver City Council, the Auditor’s Office, the Clerk and Recorder, and recreation offices will also be closed Wednesday, according to a press release from the city and county of Denver.

City and county essential services will operate, the release added.

Denver District Court is closed Wednesday due to weather, according to the Colorado Judicial Branch website. Additionally, courts and probation offices in the 4th, 8th, 17th and 18th judicial districts will be closed Wednesday. Court and probation offices in 20th Judicial District, in Boulder and Longmont, will close at noon.

A Colorado State Board of Education meeting scheduled for Wednesday has been canceled, and all state Department of Education offices will be closed, according to a Wednesday email from the board.

The Colorado Department of State is also closed Wednesday.

Southward, in the Colorado Springs metro, the city of Colorado Springs and El Paso County Combined Courts are closed, as are most major military bases.

As much as 18 inches of snow could fall in parts of Colorado and Wyoming, and wind gusts could reach 75 mph.
