(Via Weather.Com) Isaac for the first time is showing signs of becoming better organized, but is not quite all the way there yet. Aircraft reconnaissance had found a broad, elongated area of light winds in the middle of the storm with multiple tinier “centers.” A subsequent recon center location was more in the midst of the convection (thunderstorms), and that convection is deeper and more solid than it had been.

On the other hand, a NOAA tweet noted, “Most recent radar analysis shows broad, weak circulation at 2 km and possible circulation displaced at least 100 km to south at 7 km.” In other words, the low-level and midlevel centers might be discombobulated. We’ll be monitoring to see to what extent the core of the storm can consolidate and tighten up, and if so, to what extent and at what rate that leads to substantive strengthening of the storm.

– Regardless of how much the storm is able to crank up in that respect, it will be accompanied by heavy rain, and a high threat of flash flooding and mudslides will exist, especially in places such as Haiti, the Dominican Republic, and Puerto Rico where there is much hilly terrain. Furthermore, the large size of Isaac’s circulation will likely cause bands of downpours to linger well after the center passes.
