There is a risk of significant flash flooding in parts of interior SW today as deep tropical moisture associated w/remnants of East Pacific #HurricanePriscilla interacts w/jet streak associated w/an incoming trough. Risk will be highest central/northern AZ and SW UT. #AZwx #UTwx
Excessive precipitation (i.e., flash flood risk) outlook from NOAA's WPC for today (10/6/2025) as visualized on pivotalweather.com. It shows a broad region of slight risk over the interior U.S. Southwest, and a two substantial lobes of moderate risk (i.e., second-highest tier) over northern Arizona and southern Utah, respecitvely.

Next week is looking quite active in CA as a high-amplitude flow pattern develops over North Pacific in downstream response to perturbation of jet stream by West Pacific #TyphoonHalong. NorCal looks quite wet & stormy (rain & iso. tstms/mtn snow); SoCal impacts TBD. #CAwx #CAfire
Snapshot from ECMWF ensemble of an unseasonably deep low pressure system centered just west of San Francisco by early next week. It will likely bring widespread rain, isolated thunderstorms, some mountain snowfall, and possibly some gusty winds though exact path and impacts remain TBD.

this is correct. and while you would get a nontrivial one off sum from a billionaire tax (not enough for a welfare state, but a lot), the ongoing point of that tax would be prevent billionaires from existing

The entire city of Kotzebue, Alaska, is being evacuated for potential record coastal flooding. Kotzebue is the "hub" community for northwest Alaska. @alaskawx.bsky.social

Anyone have a good source of tide/inundation forecasts beyond the 48 hours on NOAA Tides & Currents site? I seem to remember that Stony Brook University used to have something, but I can't find it.

WPC has initiated Key Messages for an impending coastal storm that will look to generate strong wind gusts, heavy rainfall, and significant coastal impacts that include coastal flooding, rip currents, and beach erosion along portions of the East Coast over the upcoming weekend.

One important part of the possible coastal storm is that winds will be roughly from the NE. This is already a rare direction, and last winter featured basically zero nor'easters.

*If* ~45 mph NE gusts occur in Long Island, it could be 1000+ days since the last occurrence. Rare wind = more damage.

This extratropical transition will perturb the jet stream and could cause a major early-season rain and snowstorm in California next week. Stay tuned! #CAwx

Energy from Typhoon Halong near Japan may amplify the jet steam (excite the storm track) across the Northern Pacific / western North America this weekend. Scientifically known as tropical cyclone recurvature & extratropical transition.

We probably need to go back to ~350 ppm CO₂ equivalent for temperatures to stop rising.

We are now above 573 ppm (GHG forcing of +4.1 W/m²).

That's without aerosols cooling things down.

There's too much uncertainty to be sure, but going back to 350 ppm is already a Herculean task.

A trio of cyclonic eddies in the Gulf of Mexico are creating record-high Ocean Heat Content values for the date. Absolutely something of importance during this part of hurricane season.

Add in the fact that libraries are inherently quiet "third spaces" that provide everything from makerspaces to auditoriums and software subscriptions, and you have a winning combo

Cities are developing a new approach to developing housing: Integrating it into mixed-use library projects. These investments improve neighborhood vitality, add housing & improve services.

In new research @urbaninstitute.bsky.social, I create a database of such projects & point to success stories ⏬
Aging Libraries Could Offer Cities a Unique Opportunity to Build New Housing While Improving Public Services
Since 2000, more than 1,800 apartment units have been built in combined library-housing developments. These projects not only address local housing needs but…

Highly unusual situation approaching western Colorado with the moisture from Hurricane Priscilla. Grand Junction has never had precipitable water over an inch (25mm) so late in the year, but looks like it will be near that level on both Fri & Sat. Six standard deviations above average! #cowx 1/2
Global Ensemble Forecast System mean precipitable water and 700-mb winds valid on Saturday morning, 11 October 2025. A big plume of moisture will be transported into the southwest US ahead of decaying Hurricane Priscilla. From https://schumacher.atmos.colostate.edu/weather/ens.php Standardized anomaly of precipitable water from the ECWMF ensemble mean on Saturday morning, 11 October 2025. It shows a broad swath of  greater than +3 standard deviations in the western US. From https://schumacher.atmos.colostate.edu/weather/ecmwf.php Ensemble forecast plume showing precipitable water at Grand Junction, Colorado in the members of the ECWMF ensemble. Values are predicted to be around 25-30 mm with high confidence on Friday 10 October through Saturday 11 October, far above the 90th percentile for the date.

Pope Leo brought *Arnold Schwarzenegger* on the stage for this event.

Peak water levels in the #Miami area have been above the minor flooding threshold for the past four days, and our tide forecasts show that continuing for at least the next ten days! #KingTide

The world has lost its most powerful advocate for nature and hope. Yet many remain who will continue her legacy and I know she will continue to inspire generations more.
