According to hurricane expert Dr. Phil Klotzbach at Colorado State University, the only other time five tropical cyclones occurred simultaneously in the Atlantic was September 11-14,1971.  The all-time record is six simultaneous tropical cyclones set September 11-12, 1971

Monday marks four days past the climatological peak of the Atlantic hurricane season.  So far, we’ve had an incredible 20 named storms!  Such an incredible number of storms has only be exceeded once and that was in 2005.  In that year, the entire season had 28 named storms.

There is only one more name left on this year’s hurricane list: Wilfred.  Should additional storms develop beyond that, the National Hurricane Center will turn to letters of the Greek alphabet to name storms.

Hurricane Sally Update

As of late Monday afternoon, Hurricane Sally had strengthened to become a strong category 1 hurricane.  Sally is expected to bring life-threatening storm surge, hurricane-force winds and flash flooding to portions of the northern Gulf coast starting Monday night and Tuesday.

At 400 pm CDT, the center of Hurricane Sally was located about 145 miles southeast of Biloxi, Mississippi.  Sally was  moving toward the west-northwest near 6 mph, and this motion is expected to continue through tonight.  A northward turn is expected by Tuesday, and a slow north-northeastward to northeastward motion is expected Tuesday night through Wednesday night.  Data from reconnaissance aircraft indicate that the maximum sustained winds have increased to near 100 mph with higher gusts.  Additional strengthening is forecast tonight and early Tuesday and Sally is expected to be a dangerous hurricane when it moves onshore along the north-central Gulf coast sometime early Wednesday morning.

On the forecast track, the center of Sally is predicted to move near the coast of southeastern Louisiana tonight and Tuesday, and make landfall in the hurricane warning area on late Tuesday or Wednesday.
