The National Weather Service has issued a Flash Flood Warning on 8/7/24 until 6:30 p.m. for the Stone Canyon Fire burn scar area. Law enforcement in the area is not seeing significant impacts at this time. We have not issued a Climb to Higher Ground order, however, please pay attention to your surroundings and take action if necessary.

Radar indicated thunderstorms producing heavy rain over the Stone Canyon Burn Scar.  The expected rainfall rate is .25 inches in 15 minutes.  Flash flooding is ongoing or expected to begin shortly.  Excessive rainfall over the warning area will cause debris flows near steep terrain.  The debris flow can consist of rock, mud, vegetation, and other loose materials.

Impact includes life threatening flash flooding of areas in around the Stone Canyon Burn Scar. Locations that may experience flash flooding include Stone Canyon Road and Stone Canyon HOA. Heavy rainfall will cause flash flooding of creeks, streams, and ditches in the Stone Canyon Burn Scar. Debris flows can also be anticipated across roads.  If you encounter flood waters climb to safety.

A strong thunderstorm just developed right over the Stone Canyon burn area! The heavy rain will lead to flash flooding. Move to higher ground or get out of the area immediately! #COwx

Here's a look at the hydrograph for the Rio Ruidoso. The water will continue to race downstream toward Glencoe this afternoon. Stay safe! #nmwx

The Rio Ruidoso at Hollywood jumped into MAJOR flood stage - over 15 feet! Look at the last few frames of this video. Stay away from the river banks! It could be deadly! #nmwx

May is Wildfire Awareness Month! 🔥🔥 A recent publication with @BGCEngineering, @USGS, @UNRScience, @CalConservation, and @UniMelb focuses on post-wildfire debris flows which pose severe hazards to communities & infrastructure near and within recently burned mountainous terrain

The scale of the fires currently burning across northern Australia is pretty unfathomable.

This animation visualises just the last two months of fire captured by #DEAHotspots - for context, the map covers an area larger than France, Spain and Germany combined...

@kampf_stephanie Ugh, that’s so frustrating!! So sorry!

[Colin McCarthy @US_Stormwatch]

Satellite image of California shows virtually no smoke across the state in typical peak fire season, with fire activity confined to the extreme northwest part of the state.

Only 257,000 acres have burned across the state this year, which is 4.5x fewer acres than the 5-year average of 1.15 million.

California has experienced yet another quiet fire season so far, compared to recent years (2020 and 2021).

This past year's very wet winter, combined with very few significant heatwaves and fire weather events, has resulted in minimal fire activity outside far Northern California and the Mojave Desert.

Soil moisture across much of the state remains well above normal due to several significant moisture intrusions (e.g. Hilary) and a robust marine layer.

Personnel of the San Bernardino National Forest are conducting surveys and assessments of damage to sites and areas on the forest due to Tropical Storm Hilary’s landfall, Aug. 20-21. Read our safety messages and information about the impact of the storm at https://t.co/tZNeWaVdB9

Hi everyone! There is a new opportunity to study postfire debris flows as part of the USGS Landslide Hazards Program in Golden, Colorado! Application deadline is November 1st. https://t.co/BOXFlppugm

#Fluchthorn rock avalanche (2023-06-11) volume estimate yielded 1 Mio m³ - that makes it one of the biggest high-alpine rockfalls, and one of the few known to have decapitated a summit! 🏔️
Fascinating video about laserscan survey of the site!

The damage survey along Pikes Peak is complete and the survey team found damage consistent with an EF-1 tornado with estimated winds up to 108 mph.

Check out the graphic for more info and an estimation of the tornadoes path. #cowx
