Disastrous flooding along the San Juan River in the Four Corners region. Here’s some of what I saw today in Shiprock, on the Navajo Nation in northwest New Mexico.

A look at the damage from Saturday's tornado in Santa Fe. The tornado has been rated a high-end EF-1, with 110 mph winds. It traveled 1.4 miles, damaging 10 homes, power poles, and trees. This was Santa Fe's first documented tornado in 55 years. 📸 PNM, City of Santa Fe #NMwx

Long-term stations across the San Luis Valley in southern Colorado had their wettest 2-day period on record from the recent storms. (Yes, those numbers are correct, 2 to 2.5" in two days is record-breaking; the SLV is typically a very dry place!) #cowx

a 25 year old could not comprehend how bad the dining options were in the median American town in 1996

Historic flooding in Farmington, NM, today. Our KRQE photographer captured this video as the San Juan River reached its highest recorded level, breaking the record from 1909. Dangerous flooding continues downstream toward Shiprock, where river levels will rise tonight. #NMwx

Preliminary observations from the San Juan River at Pagosa Springs show that the flood crest above 15 feet this morning even exceeded the major floods from last October. Still below the flood of record from October 1911, however. #cowx

I point this out every year, and am often told that "surely this cannot be true!" But surveys consistently report similar numbers, and it illustrates why increasing public & private institutional visibility of individual *scientists* (not just "science in the abstract") is actually quite important.

70 percent of the internet was vulnerable yesterday to very bad security flaws inside a coding language. Turns out, *one volunteer* is mostly responsible for maintaining that code & helping push updates. Yesterday Ondřej Surý saved the internet. So I called him up www.theatlantic.com/technology/2...

Here's a more detailed look at the expected rainfall amounts through Thursday night. See weather.gov for more.

Water Year 2026 was one for the record books in Colorado. It was our warmest on record by a substantial margin, and it was also one of our driest. Our Water Year 2026 summary covers the records, trends, and impacts that were recorded across Colorado over the past 12 months. Read it here! ⬇️

As of the most recent daily NOAA OISST data (19 October), here's a GIF showing the y-axis expansion to capture recent record-breaking values in the Niño 3.4 region.

As a PhD student designing my first survey, I added what I thought was a throwaway question at the end. To my surprise, thousands of academics answered it! The paper is out today: doi.org/10.1093/pnas...

This is exactly what ICE said: "Parra-Hernandez ran in front of an ICE vehicle and was struck." Now watch the video. They're no other word for it: They're lying.

seems kind of embarrassing that they throw a big Premier League fan fest in Denver and then the local Denver network just doesn’t show the Man City/Liverpool game as scheduled, in favor of a Broncos pre-game show

With a Hurricane Warning for Isaias on the Gulf Coast, along with a Tropical Storm Watch on the West Coast for Rachel, it’s the first time the National Hurricane Center has issued watches/warnings simultaneously for both coasts. yaleclimateconnections.org/2026/10/cate...

September was extremely warm in Colorado, just shy of the monthly record. Sept also turned rainy in southern CO—record wet in spots! Link to our Sept summary below, and stay tuned for a full Water Year 2026 summary next week. [Spoiler: it was the warmest water year on record for Colorado—by a lot.]

If you lose power during Hurricane Isaias and use a portable generator, remember to run it at least 20 feet away from your home. Never run a generator indoors. Carbon monoxide is a deadly gas you can't see or smell and it can kill in minutes.

#Isaias has strengthened to a major hurricane with maximum sustained winds of 120 mph. Preparations Within the Storm Surge and Hurricane Warning Areas Should Be Completed Within the Next Few Hours. hurricanes.gov

This is wild - somebody did a deep dive into the real stories behind this famous XKCD: sheets.works/data-viz/hol...

Just did some number crunching using latest (Oct 1) ECMWF seasonal data, and I must say that I've never seen such high predictive confidence in a very wet California winter. This is a truly extraordinary forecast amid a record-strength El Niño event. [Thread: please read to end.]

Sometimes you just have to draw a line in the sand and say something is ready. I've spent the last month or so not only adding level II site functionality to Heimdall, but what I consider to be genuinely novel functionality and interactivity. It's live for you to try at heimdall.stormscale.io

Tropical moisture surging into the Desert Southwest continues a dangerous flash flooding threat across central and eastern New Mexico and the TX/OK panhandles through Thursday morning. Slow-moving storms producing heavy rainfall can quickly lead to flooding across the desert terrain. weather.gov

Just a couple hundred miles from Mexico's southwestern coast, Hurricane Polo strengthens even further. Polo has recently recorded a central pressure of 892 millibars, making it the second most-intense Eastern Pacific hurricane on record, behind 2015's Hurricane Patricia.

In the eastern North Pacific south of Mexico, Hurricane Polo has rapidly intensified from a tropical depression to a major hurricane in just over a day and continues to barrel toward category 5 strength.

Giant hail up to 4 inches (!!!) in diameter between Eads and Chivington Colorado, measured over an hour after it fell! This is the largest hail stone I have held in Colorado. #cowx #hail

It’s pretty uncommon for our area to get intense night time convection… even more so in September! Colorado weather being wild today

A highly anomalous weather pattern is likely to result in significant rainfall, first in the Southwest today, but then into the Midwest late week. First, a couple upper-level disturbances near Baja will approach the Southwest today, bringing a concentrated source of lift. (1/7)

August 2026 was our warmest on record: our 3rd record-warm month in this calendar year and the 4th for Water Year 2026. Last month featured a mix of worsening drought and localized flash flooding, as well as two tragic weather-related fatalities. Check out out our latest monthly summary for more:

NOAA data confirms that we just went through the warmest August and the warmest climatological summer (June-July-August) on record for Colorado. Stay tuned for our monthly summary (coming soon!) which will include stats on the many, many records broken this summer. #cowx

Officials have confirmed at least one person is dead after a major flash flood ripped through the Grand Canyon on Saturday. Approximately 15 remain missing.
