When a hurricane's steering winds collapse, the storm can sit in place for days, turning a wind event into a flood catastrophe. Here's why it happens.

Cities don't just run hotter than the countryside — they stay hotter after dark, and the nighttime gap is often wider than the daytime one.

The U.S. hit the top of its five-rung wildfire preparedness scale on July 18, the first time since October 2024. Here's what Level 5 actually changes on the ground.

A wildfire "complex" can bundle dozens of separate blazes under a single incident commander. The federal definition, how names get picked, and why the label says nothing about danger.

When a wildfire burns hot enough, it can build a genuine thunderstorm above itself, one that sparks new fires with dry lightning and can loft smoke into the stratosphere for months.

Wet-bulb temperature measures the limit of evaporative cooling, not just how hot and humid it feels. Here is why the number matters more than the thermometer reading.

Most people assume the white cone on a hurricane graphic shows where the damage will land. It doesn't, and that mix-up has already cost lives.

The number the National Hurricane Center assigns a storm measures wind, and only wind. History's deadliest hurricanes prove that isn't the same as knowing how dangerous one will be.

Evapotranspiration — corn's version of sweating — is quietly making already brutal Midwest heat waves feel worse, and meteorologists say the effect is only ramping up for the season.

The Weather Channel has named winter storms for 14 seasons running, using a population-and-area formula it built itself. The National Weather Service — and the AP — still won't use the names.

The same alert can mean 100 degrees in one city and 105 in the next, because heat-index thresholds are set locally, not nationally.

A flash drought can turn a healthy field into a stressed one within days, driven by heat and wind rather than a lack of rain. Farmers and forecasters are racing to catch up.

Bogus Fire. Dinosaur Fire. Not Creative Fire. Behind every odd wildfire name is a strict federal rulebook, and no committee, just whoever answers the call first.

One alert gives you up to three days of notice. The other means the National Weather Service thinks conditions are already dangerous enough to spread a fire fast. Confusing the two can cost the exact hours evacuation guides say matter most.

A technical test called additionality decides whether a carbon credit means anything — and it's now at the center of a fight over the UN's first Paris Agreement credits.

Category number measures wind. It says nothing about how long a hurricane plans to sit still, and stalling is often what turns a storm catastrophic.

Streaks of rain hang from a cloud, curl, and vanish before reaching the ground. It's a real weather event with a name, and sometimes a dangerous one.

A dry, hot stretch of weeks has pushed North Carolina into its worst drought in nearly two decades, draining the Triangle region's main reservoirs along the way.

NOAA gives the 2026 Atlantic season a 55% chance of running below normal, largely because of a strengthening El Nino. The forecast comes with an explicit caveat: it only takes one storm.

The National Weather Service quietly retired "Excessive Heat Warning" in 2025. Here's what the new terms mean, and the exact thresholds regional offices use to issue them.
