It would seem summers have been on a cooling trend over Greenland in recent summers. In 2017, a new July record low of -33C was set at Summit. Thanks to a strong +NAO last summer, 2018 has been the coolest summer for Greenland in 20 years. Frequent snowfall increased the ‘surface mass budget’ or SMB […]
With the development of Vicente and Willa, the eastern Pacific hurricane season of 2018 has entered the record books as busiest ever following a very busy season last year. Like we’ve seen all too often this year, newly formed Willa has rapidly intensified off Mexico, gaining 60 mph and gaining ‘major’ status within 24 hours. […]
It was one of those oddities of the 2018 season, you get them now and again where they go one way, the other way, up and down and just keep on going. The eventual demise of Leslie was colder waters off Portugal but like Vince in 2005 and Ophelia in 2017, Leslie defied the laws […]
According to the Met Office, the central pressure within Storm Callum dropped from 986 to 938mb within 24 hours. That astonishing 48mb drop 24 hours made Callum an ‘atomic bomb’ cyclone, doubling the 24mb within 24 hours drop to constitute a ‘weather bomb’. It also broke the 1979 record of 939mb for early October UK […]
At 12.30pm CT, Hurricane Michael made landfall near Mexico Beach, FL as a top end Cat 4 hurricane packing sustained winds of 155 mph. Just 1 mph higher would have been this the first Category 5 landfall since Andrew in 1992. Michael was the Panhandle’s strongest ever landfall and 3rd strongest for the US in […]
Despite encountering shear, some dry air and even the crossing of a cool ocean eddy, Michael has continued to strengthen. Just yesterday morning Michael was a tropical storm but as of this writing, he has become a 120 mph Category 3, poised to be one of, if not thee strongest hurricane to ever make landfall […]
Back on Friday I posted on the CAG (Central American Gyre) and the potential for development. Yesterday we had Tropical Storm Michael, today’s it’s hurricane Michael and appears to be on it’s way to becoming a major tomorrow over the open Gulf of Mexico. This system has organised and intensified quickly to the east of […]
A broad circulation of disorganized thunderstorms is affecting much of Central America from Pacific to Atlantic. This is known as a ‘Central American Gyre’ which has been known to spawn tropical cyclones as well as flash flooding and landslides. Note the low is centred over the SW Caribbean Sea but the envelop of moisture covers […]
Following an unusually cold and snowy September, that trend continued and matured into October. The 13 inches of snow which fell on Calgary was not only the city’s biggest October 1-day snowfall but was in fact the 7th snowiest of all-time. Out of the city’s biggest snow days, this event was by far the earliest […]

At 8 pm EDT Monday evening, the Central Pacific Hurricane Center elevated Hurricane Walaka a Category 5 storm with 160 mph winds, and just three […]
