KANSAS CITY, Mo. (AP) — Kansas City International Airport is warning travelers to expect delays after severe weather temporarily knocked out power.

Airport spokesman Joe McBride announced the outage around 1:40 p.m. Sunday. About twenty minutes later, McBride sent a follow-up tweet that said power had been restored but that delays should be expected.

McBride urged travelers not to call the airport to check on their flights. Instead, he says travelers should check online or call their airline.

Kansas City Power & Light reported about 60 outages, affecting nearly 1,800 customers, Sunday afternoon. The National Weather Service, meanwhile, issued severe thunderstorm warnings for about three dozen Missouri counties. Meteorologists say the storms could bring strong winds and hail.
