UK and Ireland Smacked Hard By Ophelia

My close friends in Wales report the “wheely bins” are all over the place. The obs at Dublin airport show winds have gusted to right at 60 mph during the afternoon and evening, and on Anglesey, in Wales the winds reach 65 mph! Here is a view fo the storm from the Meteosat (ctsy Univ. of Dundee’s downlink station). FYI: Ophelia is no longer a hurricane. As it moved over the much …

Satellites Show the Lack of Power In Puerto Rico as a Catastrophe Unfolds.

The images and pleas for help coming from Puerto Rico are heartbreaking and increasingly alarming. Media reports this evening are saying that 80% of the island’s crops have been destroyed. Only those with generators have power and mobile signals are sparse and intermittent. Up to 60% of people have no reliable access to clean water, and frankly, I can see no signs that much is being done about it! I …

Read These Two Essays to Really Understand What Happened In Houston Last Night

When you work as a meteorologist or a reporter, you accept that there will be times when your sleep, hunger, and comfort come far behind the importance of serving the public. Last night was one of those moments for those at the NWS in Houston, and the reporters/meteorologists at Houston TV stations. At one point the NWS office had 4 tornado warnings and at least as many Flash Flood Emergency warnings …

Freak Summer Nor’easter Headed for the Mid-Atlantic

Gale warnings in July are rare along the mid-Atlantic coast, but if a tropical cyclone is nearby, they do happen. But those are rare, and a gale warning for a nor’easter in late July? That does not happen. No way. WAY. A strong trough in the troposphere is indeed going to bring a real fall-like nor’easter to the Mid-Atlantic this weekend with winds gusting nearly 50 mph on the coast. The bigger …

Supercomputer Recreation of an Oklahoma Tornado

A big hat tip to Tim Schmit at the Uni. of Wisconsin SSEC for this: Look at the animation below of a supercell with a large tornado that was re-created using a supercomputer. From the video tag on YouTube: Using supercomputers, a team led by UW-Madison CIMSS researcher Leigh Orf, successfully recreated a monstrous supercell that produced several tornadoes in 2011, one of which registered as an EF-5 and touched …

What People Who Do Not Evacuate from A Hurricane Do Not Know

Have you been in a hurricane? I mean have you been in the eye-wall right by the eye, or in the actual eye of the storm?? Was it a category three or higher? Be honest with yourself, and think about that. If the answer is no, not really, then you have NOT been in a hurricane. I think this is why many people do not evacuate; they just do not …

Did The Euro Model Just Pull Another Forecast Coup?

Matthew is gaining strength again tonight, and Florida and South Carolina are still going to see a significant (perhaps severe) storm. If the eye stays out to sea, it will not be as bad as it could be, but if it crosses just inland, much greater damage and a major storm surge is likely. Still a rather large disagreement between the higher res. regional models and the global models today. The …

Catastrophic Flood Event Underway In Louisiana

Thousands of people have been rescued, and thousands of others are trapped by flood waters in Louisiana tonight, as over 20 inches of rain fell starting early Friday and through the weekend. I’m going to post various images/data to put some context into what/why this is happening. These floods are not yet over, and the threat is now increasing in parts of Missouri and Illinois, where up to 6 inches …

The Data is In from Ellicott City’s Flood Saturday Night. It’s Incredible.

The NWS in Baltimore-Washington posted an excellent summary of the data from the historic (and deadly) flood in Ellicott City, MD. on Saturday evening. I wrote about this flood yesterday but there is even more data now from flood gauges on area streams and more precise rainfall data. Go here: http://www.weather.gov/lwx//EllicottCityFlood2016 . The stream gauge data shows just how quickly the local streams can rise in an event like this. There has …

The Science Behind That Awesome Photo You Saw on Twitter or Facebook

Meteorologist see a whole lot more in this image however, and it even shows the promise of better warnings of severe weather. This is especially true for rural areas/ poor nations that have only a rudimentary severe weather warning system in place. The image was apparently taken from an airliner over the Pacific.  You’re looking at a very intense thunderstorm, with an updraft of air that towers into the stratosphere …
