IGOR, JULIA and KARL now Hurricanes
Hello and happy Thursday everyone. As of midday Thursday, the National Hurricane Center was issuing advisories/statements on 3 hurricanes in the Atlantic Basin: IGOR, JULIA and KARL:
IGOR: A strong category 4 storm with sustained winds near 140mph and heading toward Bermuda and likely to cause some ‘larger’ issues there by the weekend.
JULIA: A smaller, weaker category 2 storm with sustained winds of 100mph. Likely to continue falling apart as it whisks itself farther north a little faster each moment into cooler ocean water temps.
KARL: A relatively older storm, but has now retained hurricane status with its sustained winds now reaching the 75mph threshold for weaker category 1 storm classification. KARL will like make landfall tomorrow in central/northern Mexico as a weak CAT 1 or 2 storm by Friday.
Atlantic Storms to Date
Active Atlantic Basin
If it seems like we’ve been talking a lot about the tropics lately, you’re right! Typically, this is the most active part of the season, which corresponds with low wind shear in the tropics or low wind speeds in the upper levels of the atmosphere and higher ocean water temperatures where tropical systems develop. September averages 3.4 storms a year with 7 named storms averaged by the 24th of the month, 4 of which are hurricanes and 2 major (category 3 hurricanes) are also averaged by the 28th of the month.
Severe Threat Today
This is a look at the severe thunderstorm threat today. A cool front sliding through the Eastern Great Lakes and the Ohio River Valley may trigger some stronger storms in the locations highlighted in oranged this afternoon. Hail and high winds look to be the primary threat, but an isolated tornado or two can’t be ruled out.
This is the forecast high temperature map for this Saturday, September 18th. Note the cooler reading along the international border. High temperatures will struggle to get into the 50s in some of these areas in the western Great Lakes region. Keep in mind that the daylight hours in the Arctic Circle are dwindling rather quickly each day now as we near the Autumnal Equinox, so the cold pool of air is growing in this polar region. It is only a matter of time before these cold/cooler blobs of air get kicked out and head south into the lower 48
Summer continues in the southern two-thirds of the nation with 90s and triple digits in the Great Basin. If you’re looking for some heat, head down to Pheonix where the high temperature over the next few days is likely to reach 100+
That’s all for now, thanks for checking and have a wonderful Thursday!
