The American Southwest — the deadly rain, where the headline was not
CRESTING · September 17, 2026 · NO. 0917
THE WATER
A rare Moderate, level 3 of 4, excessive-rain risk over south-central Arizona and New Mexico, with three killed overnight in New Mexico, water rescues in Tucson and more than 3 inches in 3 hours near Phoenix — the same monsoon moisture that soaked Sonora, north of the border. Friday's Slight has relocated to the Four Corners; the Upper-Midwest event carried for three editions washed out. (Handled with care.)

CONNECTED
The forecast committed in one ocean and let go in the other, on the same morning — an unnamed invest became a named storm with a Tokyo target on a clean four-day ramp, while an Upper-Midwest event this page re-dated for three consecutive editions simply washed out and the water that killed people fell a continent-width away from where the story had been living.
One flood published its start time a week ago and the other arrived with no number on it at all — Nigeria's release begins today and ramps 100 to 1000 m3/s across seven days, which is lead time an agency can sequence evacuations against.
