Here is The Chance of A Major Hurricane Hitting The U.S. Coast this Year
This is really a great video from NASA, but what I like the most about it is how they explain a subtle fact of statistics that almost everyone, especially gamblers, basketball, and baseball players get wrong. With an El Nino brewing, we may see a quiet Atlantic tropical cyclone season. Like 1992, when we only had one storm make landfall on the coast of North America. Hurricane Andrew, a Category …

What Do Category 5 Hurricanes Have To Do With The Amazon River?
This freshwater plume inhibits the mixing of colder water beneath the surface, and thus can add a lot of heat to an already powerful hurricane. The NASA Aquarius satellite has a sensor that can measure ocean surface salinity, and it’s data produced the the video below. A paper about this plume and how it can affect hurricanes was published in Geophysical research Letters in 2012. It’s free to read here. …

GOES 14 Rapid Scan images of Hurricane Cristobal
This is the kind of satellite imagery we will see daily when GOES R launches in 2016, and it will be even higher resolution spatially and temporally. GOES 14 is a spare satellite that is turned on and checked out from time to time. It can take one minute rapid scan images. GOES R will be able to do this at two spots simultaneously. Post by NOAA NWS Weather …

Camille Struck 45 Years Ago Tonight
The stagnant muggy heat of August began to break 45 years ago today on the coast of Mississippi, as clouds and winds increased. Later that evening the world turned upside down as a 30 foot wall of water whipped by winds of an incredible 190 mph changed the Mississippi Coast forever.Hurricane Camille was one of the most violent hurricanes ever to hit the mainland U.S., and it still ranks with …

Super Typhoon Neogori Heads toward Japan.
The typhoon should weaken before hitting Japan, but Kyushu (southern most island) will get a ton of rain and wind. Flooding rains have already been reported earlier in the week so the soil is already saturated. ISS Astronaut Reid Wisemen sent back this shot of an oddly shaped eye on Neogori. (Perhaps related to the fact it was undergoing an eye-wall replacement cycle.)

Arthur’s Ripples
You may need to click on the image above to really see the ripples across the top of Arthur, so do that first, before I tell you why they are there. You are looking at gravity waves, but a better way of understanding it is to compare it to the ripples you see after you throw a rock into a still pond. The rock disturbs the water and makes …

The Big UK Windstorm You Will Hear About Tomorrow
There are some signs that the low may not reach quite the intensity earlier, but I would not count on that. It may indeed may be one of the strongest storms in quite sometime in Britain. Matt Taylor’s weather broadcast on the BBC is below: Click image to see it. Below is the GFS Model for 3 AM Tuesday morning. The height of the storm will likely be Monday night. …

Are Hurricane Season Forecasts Ready For Prime Time??
Weather and climate forecasts have value because decisions and plans can be made that save money, and (more importantly) lives. This is why so much research is underway into making an accurate prediction of what the rate of sea level rise will be in the coming decades, and how precipitation patterns will change as the planet gets warmer (from increasing greenhouse gases). Shorter predictions for a few months ahead can …

GOES 14 Satellite Rapid Scan Imagery of Tropical Storm Andrea Today.
The GOES R satellite will be able to do ONE minute rapid scans in two different locations when it is launched in two years! (If budget cuts don’t delay it, we will finally catch up to Europe with satellite technology.) Here is a wider shot (Visible channel) of 15 min images. Hat tip to Metr. Brad Panovich for this one: and an IR/VIS POES Image below:

NOAA: 70% Chance of Unusually Active Atlantic Hurricane Season
The NOAA outlook for this hurricane season is out. Theses forecasts have some skill but it is well to remember that SOME is the operative word here. That said there are growing indications that this will be an active year. Perhaps very active… Here is the public release from NOAA: NOAA predicts active 2013 Atlantic hurricane season Era of high activity for Atlantic hurricanes continues May 23, 2013 Hurricane Sandy as seen …
