Little Change to 99L in The Bahamas; 91L Headed Towards North Carolina

By: Jeff Masters, 04:35 PM GMT on Kolovoz 27, 2016

There is little new to say about the saga of tropical wave Invest 99L, which continued to chug west-northwest at 10 mph through the northwestern Bahamas on Saturday morning towards South Florida and the Florida Keys. Satellite loops late Saturday morning showed little change in the storm’s organization and heavy thunderstorms since yesterday; 99L still lacked a well-organized surface circulation center and the amount of heavy thunderstorm activity was modest at be...

Wait-and-See Drama With 99L Will Continue For Up to Another Week

By: Jeff Masters, 09:28 PM GMT on Kolovoz 26, 2016

The week-long wait-and-see drama will continue for up to another week with the large but disorganized tropical wave (Invest 99L) chugging west-northwest at 10 mph through The Bahamas. Satellite loops late Friday afternoon showed an increase in the storm’s organization and heavy thunderstorms, but there was no well-organized surface circulation center and the amount of heavy thunderstorm activity was modest at best. Wind shear dropped from a high 20 - 25 knots earl...

After vexing and perplexing forecasters and the public for days, the strong tropical wave dubbed Invest 99L is attempting once more to organize itself. The elongated circulation associated with 99L extends from the far southeastern Bahama Islands across eastern Cuba to just west of Jamaica. As of early Friday, 99L had failed to develop a coherent circulation, with a low-level center devoid of showers and thunderstorms (convection) spinning hundreds of miles north of...

Taking Its Time, 99L Remains a Potential Threat for Florida, Gulf

By: Jeff Masters and Bob Henson, 10:20 PM GMT on Kolovoz 25, 2016

The watching and waiting continues for Invest 99L as it rolls toward The Bahamas. 99L remained a very large but very disorganized tropical wave on Thursday afternoon. Visible satellite imagery shows one circulation near the extreme southeastern portion of the Bahamas and Turks and Caicos Islands. This circulation is largely naked, with little cloudiness around it, although some filling-in was evident late Thursday afternoon. Air Force Hurricane Hunters found winds o...

Is the Wait-and-See Game With 99L Ending? Also, Tornadoes Rip Indiana and Ohio

By: Jeff Masters and Bob Henson, 03:27 PM GMT on Kolovoz 25, 2016

A high-stakes game of wait-and-see is underway with a large but disorganized tropical wave (Invest 99L) centered near the southeastern Bahama Islands on Thursday morning. The storm brought heavy rains of 3 - 5” over the past 24 hours to portions of the Dominican Republic and Puerto Rico, and was generating winds near tropical storm force in the waters to the north of Hispaniola. 99L could become a tropical depression or tropical storm at any time over the next thr...
