Considerable flash flooding is possible across portions of New Mexico & West Texas today into mid-week. Flash flooding impacts are particularly possible near burn scars, low-water crossings & areas of complex terrain. Avoid travel through already flooded & vulnerable areas.

September 2 PM: The suburbs of Toronto just took a significant hailswath in addition to gusty winds and heavy rainfall. A lot of exposed areas were affected and this is very likely going to be quite an expensive event.

rainshadow.gif 48-hour totals are approaching 3 feet on the upslope side of the Big Island, while the areas being shadowed to the west have only seen 1-3”.
48-hour rainfall totals for the Big Island of Hawai’i are highly variable due to terrain effects. NWS and RAWS stations are plotted. Lowest total is under 1” which may be questionable, but numerous stations show 1-3” on the west side. Highest are 32.28” and 32.44” southeast of the volcanoes.

According to Morningstar DBRS, total economic losses from the French wildfires could reach €10-15 billion, while insured losses are expected to amount to several billion euros "The movement of wildfire risk toward urban and commercial concentrations is our main concern from a credit perspective."

Best way to use purpleair.com map: click on the gear icon at upper left and choose "US EPA" in the "Apply Conversion" setting, or else readings will be too high. Also uncheck the box "show inside" to avoid seeing monitors located indoors, which have a black circle around the colored dot on the map.

Smoke has arrived in Seattle, but the other side of the Cascades is absolutely brutal. Wenatchee and other towns (e.g., Plain, Entiat) have been over 1,000 AQI today. Please use air purifiers, N95 masks, and avoid being outdoors if you’re able - there is no safe level of wildfire smoke exposure.

The Prime Minister of Spain: “This climate emergency is exceeding every threshold and scale that scientists have long warned all of Spain and Europe about.” This is the realistic climate discourse the world needs. www.nytimes.com/2026/07/28/w...
"These are difficult hours," Prime Minister Pedro Sánchez said
Monday afternoon during a news conference in Castellón, on Spain's eastern coast, where a new fire raged and forced thousands of new evacuations.
In the face of what his government has called the largest fires in the country's history, and after a summer of record-breaking heat waves, he called for a national pact with all Spain's political parties to work together to prevent blazes that he attributed to climate change.
"This climate emergency is exceeding every threshold and scale that scientists have long warned all of Spain and Europe about," he said.

Here is initial info from the USGS from today's earthquake in southern Japan in Kumamoto Prefecture. This will likely be a damaging and expensive event. FYI: The 2016 Kumamoto EQ sequence (M7.0 & M6.8) resulted in $53 billion in economic losses; of which $8 billion were insured (2026 USD).
