Displaying Individual Tropical Cyclones

How to Display Individual Tropical Cyclones

The tropical season is upon us, with the seasonal peak just a few weeks away. As tropical storms and hurricanes form, our JavaScript SDK’s tropical module is perfect for displaying their track, latest position, and forecast. The Tropical Cyclone Demo displays many of the Tropical Module’s capabilities, showing users how AerisWeather can display tropical cyclones in real time. As we approach the seasonal peak in the Atlantic basin, there are often multiple active systems that may have overlapping tracks and five-day forecasts, such as this weekend, with Tropical Storm Fred and Tropical Storm Grace:   As seen, displaying tropical cyclones on a map can highlight overlapping...

Origin of “Dog Days” – Smoky US Summers On Increase Since 2016

Welcome to the Dog Days of Summer We get a whiff of Dog Days this week as daytime highs flirt with 90 degrees through Friday. Dog Days have nothing to do with an urge to pant or beg for treats, and everything to do with Sirius, the dog star – brightest in the nighttime sky. Ancient Greeks thought the star added to the heat of the sun, resulting in unbearable August heat. Of course it doesn’t quite work like that. Hazy, smoky sunshine lingers much of this week with thicker smoke the farther north and west you travel away from...

Tracking “Fred” – Racial Realities of Urban Heat Island – Key Takeaways of Latest UN IPCC Climate Report

Scientists React To Latest IPCC Report Every IPCC climate report becomes a little more dire with time as scientists draw a straight line from a doubling of planet-warming greenhouse gases since 1850 to an increase in weather extremes. During a WCCO Radio interview Tuesday, St. Thomas climate scientist John Abraham reacted to the report. “It’s unequivocal, humans are causing the warming. We are now seeing the impact on our weather. It is too late to avoid climate change, but what we’re trying to do now is avoid the worst of climate change” he said. The uptick in weather disasters is...

Peril of “Snow Squalls”, La Nina Strengthening – Eta, Theta and Iota

The Perils of Snow Squalls and a Thanksgiving Thaw Many of us become transfixed by the big snowstorms but sometimes it’s the little things. Like yesterday’s 60-minute snow burst, a “snow squall”. Prevalent downwind of the Great Lakes, these bands of torrential snow are similar to a line of summer thunderstorms: a narrow band of intense precipitation. Visibilities can fall to zero in seconds, creating mayhem on the highways. What I’ve found over the years (the hard way) is that it’s not “how many inches” of snow falls. It’s the timing, intensity and temperature of the roadway surface. A lousy...

“Eta” Takes Second Swipe at Florida – “Theta” Makes Record 29 Storms in 2020

Impressive Early Season Snowfall Tallies. Granted, most of it has melted, but 14.8″ of snow in the Twin Cities as of November 10 (more than a foot above average, to date) and nearly 20″ at Duluth? Snow lovers have to feel pretty good right about now. Maybe we’ll have a real winter, preferably without the Polar Vortex. Good Travel Weather Thanksgiving Week. Right now I don’t see any (big) storms looking out 1-2 weeks, just a series of Alberta Clippers, but little moisture available for accumulating snow. Temperature may be in the 40s, possibly 50+, depending on how quickly we...

29 and Counting: Record Year for Tropical Systems in the Atlantic (Up to “Theta”)

Snowfall Totals. Generally 3-6″ from last night’s snow burst, give or take. Click here for updated totals, courtesy of the Twin Cities National Weather Service. Odds Favor a Milder Than Average Thanksgiving. That may seem hard to believe gazing out your snow-encrusted window, but the flow looks more Pacific than Canadian Thanksgiving Week. A Very Warm Start to November. Dr. Mark Seeley breaks it down in Minnesota WeatherTalk; here’s an excerpt: “After recording mostly cooler than normal temperatures on the first day of the month, temperatures have averaged 12 to 18 degrees F warmer than normal under mostly bright, sunny...

Crazy Weather Extremes Upper Midwest – “Eta” May Take Second Pass at Florida

Plowable. Hard to believe it was in the 70s two days ago. The weather always changes fast at this latitude but…good grief. ECMWF (above two graphics) shows 5-7″ for the metro – there may be a little melting as the snow begins to fall later today, but some spots will wind up with 4-6″. Maps: WeatherBell. Moderate Pacific Flow Leading Up to Thanksgiving. I see continued troughing in the western USA, suggesting more of a Pacific breeze for Minnesota the week leading up to Thanksgiving, with temperatures are few degrees above average. In spite of today’s snow, I see no...

Record Warmth Reaches MSP – Hurricane Eta Delivers Punishing Blow to Nicaragua – Poses Risk to Florida

Colder and Stormier by Mid-Month. That’s what GFS is hinting at; maybe a few significant storms (mixed precipitation?) less than 2 weeks out as a few waves of colder air push south of the border. Category 4 Hurricane Eta Punishes Nicaragua. The New York Times (paywall) has details: “The Category 4 storm threatened much of Central America with winds of up to 140 miles per hour and rainfall that could reach 35 inches in some areas. Forecasters predicted that Hurricane Eta, whose eye began making landfall along the Caribbean coast of Nicaragua midafternoon Tuesday, would rapidly lose power as soon...

2020: Most Billion-Dollar Disasters on Record for USA – Quiet Election Day for Most of USA

Election Day Weather Preview. Most of the USA is forecast to have a quiet, relatively mild Tuesday. The only exceptions: rain for the Pacific Northwest and cold winds and snow showers and flurries across New England. Zonal Flow Spills into Mid-November? GFS guidance is a bit contradictory. The forecast for 500mb winds roughly 2 weeks out shows more of a Pacific influence, keeping temperatures close to average across most of the USA, maybe a few degrees below average for Minnesota as we end out the second week of November. Briefing: Issued Thursday, October 29th, 2020: Tropical Storm Zeta Zeta Moving...

Major Hurricane Delta Threatens Gulf Coast – Can Songbirds Predict Hurricane Energy Potential?

  Hurricane Delta Threatens Gulf Coast “Paul, has a hurricane named after the Greek alphabet ever been retired?” According to the World Meteorological Organization (WMO) that has never happened – and no, any Greek name would be reused in the future. Why is this even relevant? Hurricane “Delta” may deliver a devastating blow to Cancun today before curving north, coming ashore as a major (Category 3+) storm over coastal Louisiana or Texas Friday night. Many small towns in Louisiana still haven’t recovered from Hurricane Laura, which roared ashore August 26. “Delta” is the 25th named storm of 2020. The all-time...
