President-elect Donald Trump will take the oath of office from inside the Capitol Rotunda on Monday due to forecasts of intense cold weather, upending months of meticulous planning for a massive outdoor event with crowds sprawling down the National Mall.

President-elect Donald Trump said his inauguration will take place in the Capitol Rotunda due to dangerously low temperatures.

Bitter cold – along with a chance of snow – is in the latest forecast for President-elect Donald J. Trump's Inauguration Day.

The Rotunda is prepared as the inclement weather alternative for each inauguration in the event of inclement weather. The swearing-in was last moved indoors in 1985, when President Ronald Reagan began his second term. Monday’s forecast calls for the lowest inauguration day temperatures since that day.

The coldest inauguration on record was President Ronald Reagan’s second swearing-in ceremony in January 1985, when the temperature was 7 degrees, followed by President Ulysses Grant’s ceremony in 1873 at 16 degrees and President John F. Kennedy’s ceremony in 1961 at 22 degrees.

The high temperature for the day is projected to be below freezing, at 24 degrees, and could drop to a low of 9.

President-elect Donald Trump announced that he has ordered his inauguration ceremony to move inside the U.S. Capitol rotunda on Monday, Jan. 20, due to dangerously cold weather

The second inauguration of Ronald Reagan on Jan. 20, 1985, was forced indoors due to intense cold. As USA TODAY noted that day, "The USA's 50th inauguration today moves indoors – a victim of bone-chilling temperatures that threatened 350,000 invited guests and parade watchers."

Donald Trump announced the change to his plans on TruthSocial, pointing to a wind chill forecast by the National Weather Service forecasting 'severe record lows' on Monday.

The decision means the 250,000 people who had tickets to view the inauguration outside will no longer be able to do so - with a live viewing now taking place at the nearby Capital One Arena.

The unseasonably cold temperatures could impact preparations for inauguration events and create hazardous commuting conditions.
