Three’s a Crowd

17 Sep 2010, 10:59 am

Pre-season forecasts for an active hurricane season are coming to fruition. As I’m writing up this morning’s blog, we’re watching THREE hurricanes churn in the tropics. Igor is a strong category 3 storm, packing winds sustained around 120 mph. This major hurricane is forecast to track toward the northwest, making a direct beeline for Bermuda by Sunday night. Hot on Igor’s heels, Julia continues to hold her own. A minimal category 1 storm, Julia will continue to weaken thanks to Igor’s influence on the surrounding atmosphere. Julia may weaken enough to drop to tropical storm status by Saturday afternoon or evening. Finally, Hurricane Karl is making landfall near Veracruz, Mexico as a category 3 storm, with winds sustained at around 120 mph. Karl is forecast to bring the central and southern Mexican coast around 5 to 10-inches of rain, leading to a threat for mudslides.We’re into the last several days of summer, and fall is trying to make an early entrance in parts of the country. Highs in Minnesota, the Dakotas, and Montana will struggle through the 50s and 60s today. Meanwhile, snow is flying in the upper elevations of northern Montana. A winter weather advisory is in effect for Glacier National Park through this evening. 6 to 8-inches is in the forecast above 6,000 feet, with 2 to 4-inches down to around 5,000 feet. This photo below is a wintry morning view from the Two Medicine webcam in Glacier National Park. By the way, the Autumnal Equinox officially arrives Wednesday, September 22 at 10:09 A.M.Speaking of equinox, how about a quick explanation of we are watching this time of year. The Earth’s axis has been tilted, allowing for the sun to shine its most intense rays across the northern hemisphere over the summer months. As we tilt neither away from nor toward the sun, the sun’s rays slide directly over the equator. This happens during the vernal(spring) and autumnal(fall) equinox. Our current shift will allow the sun’s most intense rays to shine down over the southern hemisphere over the next several months, giving those in the southern hemisphere spring and summer, while providing those of us in the north our fall and winter seasons. Hope you have a fantastic Friday!
