5:20 p.m. Update: The FAA reports that the Cincinnati/Northern Kentucky airport has reopened. However, delays are spreading. They are affecting the following airports: Reagan National, Atlanta, Boston, Indianapolis, John F. Kennedy International and Newark.

Original post: The Federal Aviation Administration said that Cincinnati/Northern Kentucky International Airport is closed as of 4:30 p.m. following a widespread outbreak of severe weather.

The FAA did not provide a time as to when the airport is expected to reopen.

The Post’s Capital Weather Gang said tornadic thunderstorms were in place south of Cincinnati. Weather editor Jason Samenow said that 37 tornadoes have been reported today as of 4:30 p.m.

Weather is also affecting flights headed for other airports. Flights destined for Logan International Airport in Boston and Newark Liberty International in New Jersey were being affected by low ceilings and were delayed 33 minutes to almost an hour. Traffic destined for Chicago O'Hare is experiencing average delays of more than two hours due to snow and ice.

In the D.C. and Baltimore regions, the National Weather Service has issued a flood watch effective until Saturday morning. The ground is currently saturated, officials said, which could cause streets to flood and creeks to overflow their banks.
