An Agricultural “Island” in the Saskatchewan River Delta - NASA Science (opens the original)
Read excerpt
Surrounded by wetlands, Manitoba's northernmost farmland near The Pas turns from green to brown over the 2026 growing season. Much of the Saskatchewan River Delta, a large inland delta that straddles the Canadian provinces of Saskatchewan and Manitoba, is too wet for extensive farming. But amid the delta’s winding channels, lakes, and marshes, an “island” of straight-edged fields breaks up the curvy contours. These fields, west of the town of The Pas, make up Manitoba’s northernmost agricultural
Fire Cloud with a Pileus on Top - NASA Science (opens the original)
Read excerpt
Scientists captured rare observations of an ephemeral pileus cloud hovering over a smoke-infused cloud that rose above a wildfire in Montana. In summer 2026, scientists took to the air to intercept and study the towering, smoke-infused clouds that wildland fires sometimes create. But during an August 11 flight over the Sand Creek fire in Montana, they came back with a bonus—observations of an ephemeral pileus cloud hovering atop one of the towering fire clouds. Smooth, veil-like pileus clouds ar
Explosive Intensification for Hurricane Polo - NASA Science (opens the original)
Read excerpt
Several ingredients came together off the Pacific coast of Mexico to generate one of the strongest storms the eastern Pacific basin has ever seen. In mid-September 2026, Hurricane Polo began as a tropical disturbance off the Pacific coast of Mexico. By September 20, it was organized enough to qualify as a tropical depression, and by the next day it was a tropical storm. From there, Polo launched into a period of rapid intensification that left meteorologists searching for adjectives strong enoug
Cloudy Cloak Over the Northwest - NASA Science (opens the original)
Read excerpt
A low-lying cloud layer brought autumn ambience to western Washington and Oregon, while mountainous areas near the coast remained above the pall. Cool, marine air rolling off the Pacific Ocean led to a picturesque layer of morning clouds over western Washington and Oregon in mid-September 2026. Low-lying stratus clouds and fog extended as far inland as the western foothills of the Cascade Range. Near the coast, taller portions of the Olympic Mountains in Washington and the Oregon Coast Range app
Summer Goes Out With a Heat Dome - NASA Science (opens the original)
Read excerpt
Temperature records toppled across the central and southern U.S. as the autumnal equinox approached. While the calendar indicated that astronomical summer was winding down, a swath of the south-central United States was sweltering under a heat dome in mid-September 2026. This map shows air temperatures in the contiguous U.S. on September 15, 2026, at 4 p.m. Central Time (21:00 Universal Time), modeled at 2 meters (6.5 feet) above the ground. It was produced by combining satellite observations wi
