Aug 22: Watching the Tropics Closely

Tropical development near the Leeward Islands of the Lesser Antilles has been hindered and stunted by it’s surrounding environment. It will likely remain disorganized as it passes over/just to the North of the Greater Antilles. It will then turn northwards and intensify before likely re-curving out to sea. I’m not prepared to say how far or close it will come to the east coast as uncertainty is very high beyond 72 hours of model guidance. At this point you cannot rule out fringe impact to the east coast (intensified surf, outer-band precipitation, etc). Such impacts would be expected early to mid-week.

Weather NJ tropical guidanceThe latest spaghetti plot (all operational tropical model projected paths displayed on same map image) shows high certainty that this system will steam towards the Bahamas region throughout the course of this weekend. There is high uncertainty beyond that due to a complex interaction involving an upper-level trough of low pressure and a ridge of high pressure. The mean of this guidance indicates a general re-curve out to sea which makes the most meteorological sense. I know some of the paths indicate a Sandy-like track but take those with the grain of salt for now. We won’t know the true expected east coast impact until probably Sunday. In the meantime, have a great weekend. You know I’ll be tracking. Be safe! JC
