DISCUSSION
-----------------------------------
Tropical Storm Gretel continues southeastward very quickly and is now located far north of New Zealand's North Island. This system is currently producing convection displaced towards the southeast under high wind shear and  the system continues to weaken. Latest microwave pass indicated that this system's convection is heavily displaced to the southeast. Wind shear is high at over 40KTS and set to exponentially increase even further, making it unfavorable for tropical development. Sea surface temperatures is unfavorable at 25C and expected to drop even further. Models are indicating that this system is expected to move southeast while remaining well north of the North Island of New Zealand. Global dynamical and statistical models forecast this system to weaken slowly while still attaining gale force winds as an extratropical low. Metservice New Zealand indicates that this system is expected to move southeast and degenerate into an extratropical low.
