About 60% of the Midwest and northern Great Plain states are in a drought. Nearly the entire stretch of the Mississippi River — from Minnesota to the river’s mouth in Louisiana — has experienced below average rainfall over the past two months.

Of the three main types of heat-trapping greenhouse gases — carbon dioxide, methane and nitrous oxide — the biggest jump from 2020 to 2021 was in methane, whose concentrations in the air came in with the biggest year-on-year increase since regular measurements began four decades ago, WMO said.

Lack of rainfall in recent weeks has left the Mississippi River approaching record low levels in some areas from Missouri south through Louisiana. The U.S. Coast Guard said at least eight “groundings” of barges have been reported in the past week, despite low-water restrictions on barge loads.

Floodwaters rose waist-high near Orlando as one of the strongest hurricanes to ever hit the United States crossed the peninsula. Ian's tropical-storm-force winds extended outward up to 415 miles, drenching much of Florida and the southeastern Atlantic coast.

About 2.5 million people were ordered to evacuate southwest Florida before the storm hit the coast with maximum sustained winds of 150 mph. It was heading inland, where it was expected to weaken, at about 9 mph, but residents in central Florida could still experience hurricane-force winds.
