Atlantic - Nadine forms October 9, 2018 (days, storms, most, moving)

[Psychoma]

9Oct18 11aEDT/AST: On Tuesday morning Tropical Depression 15 formed and by 11am has become Tropical Storm Nadine in the far Eastern Atlantic off W Africa.

11pEDT/AST: Estimated winds 45mph(75km/h), moving NW 8mph(13km/h), pressure 1003mb.

Expected to strengthen some over the next day or so then gradually weaken as interacts with a trough, increasing shear, and eventually cooler waters. Official NHC forecast has it dissipating this weekend but has it getting to a strong Tropical Storm prior to then. There is some disagreement in models on track in a few days. Will watch for what it does in a few days.

12Oct18 5pEDT/AST: Estimated winds 40mph(65km/h), moving WNW 15mph(24km/h), pressure 1003mb. Under high shear and weakening, expected to become a remnant Low pressure system soon. Not currently expected to recover any but we'll watch as it's remnants steadily trek towards the Caribbean.

Kind of left its storms behind this evening...just a naked lower level swirl with most clouds/storms all off to its NE:
