Almost 200 flights into, out of or within the US at Chicago O’Hare International Airport have been delayed today, according to FlightAware.

Much of Illinois and Iowa are under severe thunderstorm and flood watches this afternoon.

Meanwhile, some 50,000 people will be passing through airports today as Memorial Day weekend begins, according to Secretary of Transportation Pete Buttigieg.

Chicago O’Hare International Airport has seen nearly 100 delays so far on Friday, according to FlightAware.

This uptick comes as severe thunderstorms hit much of Iowa and Illinois, bringing wind gusts up to 80 miles per hour, hail and tornadoes

O’Hare is the fourth busiest airport in the US, meaning today’s storms could continue to impact Memorial Day travel throughout the country.

The storms expected to hit Oklahoma and Texas today will bring two-inch hail — the size of a hen’s egg — to the region, the National Weather Service said.

Egg-sized hail can easily damage cars and homes.

The region will also see wind gusts of up to 70 miles per hour.

Meanwhile, hurricane-force winds and tornadoes could hit the central US this afternoon.

These weather hazards come on the second day of Memorial Day Weekend travel and could create delays at airports across the country.

Areas of several states, including Texas, New Mexico and Arizona are under red flag warnings for extreme fire danger this weekend.

These conditions are exacerbated by high winds, low humidity and ongoing drought conditions in the southwestern US, according to the National Weather Service.

On Thursday, the US Bureau of Land Management (BLM) issued a warning to celebrate Memorial Day responsibly — and a reminder that fireworks are banned on BLM-managed public lands.

Memorial Day, which also marks the unofficial start to summer, is observed annually on the last Monday of May, with most Americans receiving the day off from work.

The nation commemorates the holiday with a service at Arlington National Cemetery in Arlington, Virginia, with the president typically laying a wreath at the Tomb of the Unknown Soldier.
