The disturbance that I mentioned in my previous update on Tuesday has since been upgraded to TS Danny and has tracked northwest toward the southeast US coastline. As of this morning, Danny was located about 350 miles south of Cape Hatteras NC and heading NW at 9kts. The storm has consistently been poorly organized, with an exposed low-level center and the convective activity displaced to the east of the center. Latest intensity is 35kts and 1008mb, and that is not expected to change much as it makes its way toward the coast then gets pushed out northeastward, scraping the US/Canada coast.
Danny is forecast to be near Cape Hatteras overnight tonight, then near Cape Cod on Saturday evening, over Nova Scotia on Sunday morning, and Newfoundland early Monday morning. However, the effects will likely be minimal since it's not a strong storm and it'll be moving rather quickly.
Elsewhere, another easterly wave exited the African coast on Monday and has gradually gotten better organized. It's located about 650 miles WSW of the Cape Verde islands and has a 1010mb Low embedded in it. It is strongly favored by computer models to become the next hurricane by the end of the weekend as it heads WNW toward the Lesser Antilles.
And finally, an easterly wave is just now exiting Africa today and also shows signs of development. The next two names on the list are Erika and Fred.
