Tropical storm Nana is getting sheared to pieces!!! The western half of the storm is exposed as the strong upper level westerlies are killing the storm... Even the NHC expects Nana to be a remnant low in 48 hours, if not sooner... Even if the shear relaxes in the long term and Nana redevelops I'm pretty much a 100% sure now that it will head out to sea... I thought it had a good chance of slipping under the weakness in the Atlantic but it obviously developed to quick... 9 out of 10 times if a system is named before 40 W it will feel the weakness and head out to sea... Nana is not a threat to the US which is great news!
98L in the Caribbean also doesn't look like a threat to the US... All the global models show 98L heading out to sea... Also the HWRF and the GFDL show what will become Omar heading out to sea as well... Both the HWRF and the GFDL do have Omar hitting near Puerto Rico as a tropical storm... After hitting Puerto Rice Nana should get picked up by a trough which will cause it to accelerate to the northeast... It probably will become a hurricane briefly, but even Bermuda is safe as Omar looks to head way east of there... Again this is good news!
