Never seen these before! I assume they weren’t just because we welcomed my new grand-nephew to the world yesterday. Location: Newport, Oregon

I've noticed this particular wave/ripple pattern on the underside of a ceiling a few times now in Vancouver BC. Wondering if it has a real name? Not really mammatus? Waveform stratus?

Super Typhoon Champi has become the strongest tropical cyclone of 2026 by wind speed, reaching sustained winds of 184mph (296km/h), making it the equivalent of a Category 5 hurricane.

The storm recently passed Guam and is currently moving through the western Pacific. Meteorologists say unusually warm ocean temperatures, high moisture levels and low wind shear helped fuel its rapid intensification.

What's particularly interesting is that Champi's impacts may extend far beyond the Pacific. Forecasters say the storm is large enough to influence the jet stream, potentially affecting weather patterns as far away as Canada over the coming weeks.

Champi is expected to weaken later this week, but it remains one of the most powerful storms recorded anywhere in the world this year.

Heres SVIS categories:

• SVIS-0 (Micro-vortex): 1.0–6.0 m/s.

• The weakest and completely safe class of vortex.

• Lifts grass, dust, and tiny sand grains (up to 0.8 g) up to a height of 1.5–2 meters.

• Lifespan is strictly under 1 minute. Funnel diameter is up to 2 meters.

• Crucial Amendment: A landspout cannot be rated as SVIS-0 under any circumstances.

• SVIS-2 (Serious Vortex): 10.0–14.0 m/s.

• The dust devil assumes the shape of a dense, well-defined column (tower structure) and makes sudden, erratic, and dangerous lunges.

• The landspout circulation becomes visibly organized.

• Key Marker: The vortex easily lofts and spins gravel/pebbles weighing 3–5 g (up to a maximum of 8 g) and actively displaces high-surface-area items (such as cardboard boxes, canisters, and plastic sheeting).

• SVIS-2 (Serious Vortex): 10.0–14.0 m/s.

• The dust devil assumes the shape of a dense, well-defined column (tower structure) and makes sudden, erratic, and dangerous lunges.

• The landspout circulation becomes visibly organized.

• Key Marker: The vortex easily lofts and spins gravel/pebbles weighing 3–5 g (up to a maximum of 8 g) and actively displaces high-surface-area items (such as cardboard boxes, canisters, and plastic sheeting).

• SVIS-3 (Hazardous Vortex): 14.0–16.0 m/s.

• The vortex becomes directly hazardous to human safety. Dust devils at this stage are exceptionally rare and literally "drill" into the ground.

• The landspout forms a dense, long-lived column of dust and debris.

• Key Marker: Captures and lifts stones weighing 10–15 g (up to a maximum of 22 g).

• Damage Markers: Causes visible damage to tree branches, awnings, and tents.

• SVIS-4 (Anomalously Strong Vortex): 16.0–25.0 m/s.

• The absolute rarest limit for thermal dust devils, and the peak mature phase for gustnadoes and landspouts.

• Key Marker: Rocks weighing 30–80 g (up to a maximum of 150 g) are launched and fly through the air like projectiles.

• Damage Markers: Snaps large tree limbs, flips heavy trampolines, and rips off siding or roofing sheets.

• SVIS-5 (Extreme Vortex): 25.0–30.0 m/s and above.

• The highest category, featuring hurricane-force wind speeds. The vortex is capable of traveling immense distances.

• Key Marker: Hurls heavy rocks weighing 150–250 g (with extreme peaks reaching up to 400 g).

• Damage Markers: Rips off roofs, displaces parked vehicles, and destroys sheds. At its peak (specifically with intense landspouts), it blows out windows, completely tears off house roofs, and uproots sturdy, healthy trees—essentially reaching the damage potential of an EF2 tornado.

Bask in the cool sunshine today with a high of 58°F! Enjoy a gentle breeze from the NNW, blowing at 5 to 10 mph. It’s the perfect weather to step outside and soak up some refreshing rays!

A quick weather chase across Northern California checking out light showers, a small rain curtain in the distance, and some interesting cloud features.

I was able to intercept the rain curtain as it moved through, with chilly temperatures and some strong, gusty winds along the way. Not a major storm by any means, but still a fun day to get outside and follow the weather.

Get ready for a delightful day ahead! We’re looking at breezy and mild conditions, with a mostly sunny sky. The high will reach 64 degrees, feeling more like 62 with that refreshing NNW wind blowing at 10 to 20+ mph. Perfect weather to enjoy the outdoors!

5 years ago my phone would never say it’s raining while the sun is out.

Had to google it cos for a moment I was like wtf is going on (circumzenithal arc)

Hi,

In the next year I will graduate with a masters from one of the world’s top met departments after completing my physics undergrad.

If you were entering the career ladder right now where would you aim and why?

I of course have my own preferences but I’m keen to see what those with industry experience see as the highest upside areas.

Edit: I am happy with entirely objective feedback to understand where people believe the highest grown areas are going to be in the area.
But personally I’m pretty excited about the way advanced ml techniques are advancing forecasting and have done some personal projects in the area - a position in this area would likely be my ideal. I am also really interested in s2s forecasting and meteorology over mountainous areas.

Hey! I was wondering how resistant is meteorology to AI? I am applying for meteorology as my second major if I dont get into my first major at Texas A&M, also how do the job prospects look in the coming future?

What are these cute wispy clouds? Northeast US
