I'm a CMU Honors student and love meteorology and extreme weather. I've been fascinated by weather since I was 5, and plan on becoming a meteorologist

Over the past few days tropical storm Nadine has been making the transition from tropical to extra-tropical. On satellite Nadine looks extra-tropical but there is probably still some warm core characteristics. Currently Nadine has 50mph winds, a 993mb pressure, and is moving N at 5mph. Cooler waters and high wind shear have made Nadine to continue to weaken. With Nadine not being fully tropical she will behave a little different than to a fully tropical system up here. Some of the indicators for determining cyclone strength suggest Nadine is also turning extra-tropical. She still has a well defined circulation with tropical storm force winds tropical or non-tropical. She should be able to hold her strength more and models don't show much in the way of intensity change. As for track models are unsure of were Nadine will go. The ECMFW(European) model takes Nadine to the west but I think this is unlikely. A more likely solution is a turn to the east and even SE and possibly hit Europe of N Africa. People in the Azores need to be ready for some sort of TS conditions and TS warnings are in effect.
An area of showers and thunderstorms east of Bermuda needs to be watched. Even though they are associated with a non-tropical low the low could pick up tropical characteristics. As long as it stays over warm ocean waters it has a chance of getting named. Currently the low is moving west at 10mph and is no threat to land.
My Atlantic Outlook
TD Lane is quickly weakening over the open waters of the Eastern Pacific. Cool SST's and shear have quickly weakened Lane from a hurricane to a tropical depression. His center is completely void of convection and this should not change. Currently Lane has 35mph winds, a 1009mb pressure, and is moving WNW at 9mph. Lane should continue to weaken over the next couple days. In a couple days Lane should be a remnant low and he is no threat to land.
Have a great Wednesday and I'll have a tropical update tomorrow and my Isaac and Saffer Simpson scale blog out in the next few days.
