(1/4) BIG ANNOUNCEMENT! Earlier this summer, I made the difficult decision to retire from my position as Director of the @millersvilleu Weather Center at the end of August. I’ve been blessed to serve in this role for one-third of a century (yikes!) and to be part of…

Jersey will dry out and rise again quickly. They always do. This is not the first time nor the last. Barrier islands are always transforming from high tides and storm-driven flooding.

For the first time since 1914, the Atlantic hasn't seen a single hurricane by September 21.

This is the craziest tornado video I've ever seen! It literally gives you a front row seat to an EF3. The flying debris would be deadly for anyone not below ground when this tornado hit...

China's helicopter reached the spot where the glacier had broken, and the water released from it had caused massive destruction in Nepal. This event is called a GLOF. Glacial Lake Outburst Flood (#GLOF) can occur when the dam of a lake held back by a glacier suddenly bursts. releasing millions of cubic meters of trapped water. China | Tibet| Nepal #NepalFlood
Readers added context they thought people might want to know
The video is not from a Chinese helicopter over a glacier break in Nepal. It shows a glacial lake outburst at Alaska's Columbia Glacier, per original footage by pilot Leigh Coates. lavanguardia.com/vida/20260827/… youtube.com/watch?v=floh1L…

Here's what happened...

🇳🇵🚨 The USGS says that the seismic signal initially recorded as an earthquake in Nepal was actually caused by a powerful landslide: an avalanche of ice and rock from a glacier, and not by a natural tectonic movement.

The pronounced hook echo on radar did produce. Nice catch Jeremy!

Finally, the official storm report for July 4th wind event centered on Manheim Twp (Lancaster county). Not a tornado, but extreme straight line winds from a downburst…which caused tornado-like damage.

Today’s weather: “Gusty winds with blowing & drifting gypsum!” Seriously, folks, this isn’t snow—it’s the gypsum dunes of White Sands National Park in New Mexico. A surreal day driving and hiking here.

Pittsburgh looks like it could be located in the Arctic Circle in this photo from last night. The melting and cracking ice made for a ton of interesting shapes and textures. I always look forward to this happening any time we get ice on the rivers. Sure it's interesting when they completely freeze over but when they start looking like this it really makes for some fun photos! #pittsburgh

Looks like the Arctic Ocean — it’s really Lake Erie!

Below −20°C along the shores of Lake Erie. ❄️✨ The water is frozen solid, wave after wave locked in ice, stretching as far as the eye can see. A place that never truly rests, even in deep winter.

Lake Erie nearly 100% frozen — about a once-per-decade occurrence.

👀 I was checking out Lake Erie's ice on the satellite... Check this out... You can see a giant crack forming on the ice sheet from near Long Point #Ontario to #Cleveland, OH!

Just incredible scenes in North Myrtle Beach. Love it or hate it, take a moment to appreciate what is happening. Between the incredible snowfall totals many will wake up to, and the extreme cold, this storm will join the ranks of legends like the 1989 storm. #SCwx #NCwx @wmbfnews

It’s not any day that you can stand in the middle of the Conestoga Creek! Only one or twice per decade do we get the sustained cold needed to create this ice rink! Today is the 8th consecutive sub-freezing day and 4th single-digit overnight.

Sunday's snowfall summary: Most common across Lanco was 8 - 10 inches of snow/sleet. High reports were in Mountville (12") & Denver (13"). Statewide, there were widespread reports of 14 - 18" in central & northern counties. The jackpot: Laurel Summit (Westmoreland Co.) with 24"!

In my 40+ years in the weather biz, I don't recall hearing of a significant avalanche in Pennsylvania! This happened yesterday in Luzerne County, where 17" of snow fell.

Prepare, my friends, for immense hype on a potential "B word" next weekend. Yes, there is one model that shows that possibility, however, the model consensus has the storm tracking well offshore (so a "miss"). Time will tell.... REMAIN CALM. 😉
