The earliest “C” Atlantic tropical cyclone on record is unleashing catastrophic flooding across Central America and threatens to deluge the US Gulf Coast this weekend through early next week. Tropical Storm conditions appear increasingly likely beginning this weekend from Louisiana to the Florida panhandle. Cristobal was ravishing southeast Mexico, Guatemala and El Salvador Thursday afternoon despite weakening into a tropical depression over the rugged terrain of the Yucatan Peninsula. Rainfall on the order of feet has fallen over portions of Guatemla, El Salvador, and Southeast Mexico since last Friday’s initial onslaught of Tropical Storm Amanda, whose remnants redeveloped into Tropical Storm Cristobal on Tuesday. El Salvador alone has reported 27 deaths from flooding, mudslides, and structural collapses since Friday, a figure that is undoubtedly on the rise with an additional 10-20″ of rain on the way for Central America. Storm totals are expected to approach 35″ through Saturday, when Cristobal’s…

June 1 marks the first day of Atlantic Hurricane season and for the sixth year in a row it is already off to an early and active start. Tropical Storms Arthur and Bertha have already been named, with Bertha on May 27th becoming the first named tropical cyclone to make landfall in the US of the 2020 hurricane season – before it had even officially started. If a third tropical cyclone develops in the Gulf of Mexico this week it will become the earliest named tropical system on record, and could possibly become the season’s second US land-falling tropical system. An active subtropical Pacific jet stream throughout the winter deflected most cold shots from reaching the Gulf of Mexico, Caribbean, and Subtropical Atlantic. The mild winter left Sea Surface Temperatures (SSTs) above normal at the start of spring, giving the Atlantic Basin a head start to reaching the 26°C (79°F)…

It will feel more like March than May this weekend as the Polar Vortex dislodges from the Arctic and passes directly over the Northeast. Record cold and even a rare May snowfall will make for a stark contrast to the recent mild winter. Low pressure from the Ohio Valley will inaugurate the arrival of the Polar Vortex with rain changing to snow across much of the interior. The rain will work its way northeastward throughout the afternoon and evening as the low darts toward the Gulf of Maine. A powerful cold front will sweep across the Northeast behind the low’s passage. It will change rain to snow across most of northern and central Pennsylvania, southern and eastern New York State, and northern New Jersey in the evening and across New England overnight. High elevations in Pennsylvania and southern New York, especially those over 1500 feet in the Poconos and the…
