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


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...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3401">Read More</a>

Still Too Soon to Write Off Struggling 99L


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...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3400">Read More</a>

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


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...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3399">Read More</a>

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


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...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3398">Read More</a>

Huge 99L Generating 55 mph Winds, But Remains Disorganized


A huge and powerful tropical wave (Invest 99L) is generating winds of tropical storm force near the Virgin Islands, and could become a tropical storm at any time over the next two days as it heads west-northwest at 15 mph towards The Bahamas. If 99L develops a well-defined surface circulation, it will be called Tropical Storm Hermine. An Air Force hurricane hunter aircraft was investigating 99L early Wednesday afternoon and found sustained surface winds of 50 - 55 m...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3397">Read More</a>

99L Poised to Become Tropical Storm Hermine


Invest 99L is already bringing winds of tropical storm force to the northern Lesser Antilles Islands, and it could become a tropical storm at any time over the next day as it heads west-northwest at 15 mph towards Puerto Rico and the Virgin Islands. At Barbuda, sustained winds at minimal tropical storm-force—39 mph—were observed at 7:18 am AST, with a wind gust of 45 mph. At 10 am AST, Princess Juliana Airport in St. Maartin recorded sustained winds (below tropi...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3396">Read More</a>

Unwelcome Rains Will Put Stress on Lake Okeechobee’s Dike


A steadily organizing Invest 99L was bringing heavy rains and strong wind gusts to the northern Lesser Antilles on Wednesday morning, and is an increasing threat to develop into a tropical storm. Even if 99L never develops into a tropical cyclone, it has the potential to dump a large amount of rain on a place that doesn’t need it—the catchment basin of Lake Okeechobee in Central Florida. The huge lake represents an important source of fresh water to South Florid...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3395">Read More</a>

Still-Disorganized 99L Remains a Threat to Southeast U.S. Coast; Gaston Growing


A large and strong tropical wave about 250 miles east of the Lesser Antilles, Invest 99L, continues to move west-northwest at about 20 mph on a course that would bring it within striking distance of the southeast U.S. coast by late in the weekend or early next week, quite possibly at hurricane strength. Venturing into 99L on Tuesday, Air Force Hurricane Hunters found that the wave had an poorly defined circulation, elongated from north to south. Often it will take o...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3394">Read More</a>

Threat to Southeast U.S. Growing From 99L; Gaston Forms in Eastern Atlantic


The Hurricane Hunters are in the air, investigating Invest 99L, a steadily organizing tropical wave that was located about 300 miles east of the northern Lesser Antilles late Tuesday morning. This storm will bring heavy rains and gusty winds to the northern Lesser Antilles Islands Tuesday evening through Wednesday, and is likely to develop into a tropical storm or hurricane that will affect the Bahamas and the Southeast U.S. coast late this week or early next week. ...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3393">Read More</a>

99L a Potential Threat to Hispaniola, Bahamas, U.S. East Coast


The main Atlantic tropical weather threat to populated areas continues to be Invest 99L, a large tropical wave with an increasing amount of heavy thunderstorm activity that was located about 800 miles east of the northern Lesser Antilles Islands late Monday morning. This disturbance was moving west to west-northwest at 15 - 20 mph, and will bring heavy rains and gusty winds to these islands beginning on Tuesday evening. Conditions for development will steadily impro...<br /><a href="http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3392">Read More</a>
