The tropics continue to be active. Overnight one additional wave formed off the remnants of Florence that could eventually gain tropical or subtropical characteristics.

 

 The two "outermost" waves will take closer to five days to develop, but the middle wave (Invest 90) has a 70% chance of developing those tropical or subtropical features within the next 48 hours, however, current projections show it simply meandering in the north-central Atlantic and not making progress toward land.

 Off the coast of Africa, Tropical Storm Kirk hasn't strengthened much overnight, but it also hasn't weakened. It's holding onto it's Tropical Storm status and is moving rather quickly off to the west.

 That quick movement is good for us, but bad for the storm. While Kirk will move over warmer water that typically makes tropical systems stronger, because it's moving so quickly, it won't get as much energy and strength from that warm water compared to if it were moving slower.

Kirk will gain *some* strength over the next few days, and some of that is from the warm water, but also low wind shear. As it approaches the Caribbean however, that very strong wind shear is forecast at this point at time to put a stop to any major developments into late this week. Keep it tuned for the latest updates on Kirk from the NBC2 Hurricane Tracking Team.

That strong wind shear is also taking it's toll on Tropical Depression Eleven. Eleven is incredibly ragged this morning, and will likely not make it through the night.
