FYI-Tropics Update: Friday Notes on Hurricane Kirk and Tropical Storm Leslie


Summary

·         At 4pm CDT Thursday, Isaac weakened into a Tropical Depression over northern Louisiana and the National Hurricane Center issued the last advisory on the storm.

·         As of 5am EDT Friday, Hurricane Kirk was located in the central Atlantic about 835 miles east of Bermuda.
·         Hurricane Kirk is moving to the north-northwest at 12 mph and maximum sustained winds have increased to near 105 mph, making Kirk a Category 2 Hurricane on the Saffir-Simpson Hurricane Wind Scale.
·         Some fluctuation in strength is forecast today, but Kirk will likely begin to weaken tomorrow.
·         Kirk is forecast to curve northward and then northeastward today and will stay over the open waters of the Atlantic Ocean through the next five days.

·         As of 5am EDT Friday, Tropical Storm Leslie was located about 940 miles east of the Leeward Islands.
·         Maximum sustained winds have increased to 65 mph. Additional strengthening is forecast and Leslie could become a hurricane later today or tonight. There is currently a 14% chance that Leslie may reach Major Hurricane strength within the next five days.
·         Leslie is moving toward the west-northwest at 16 mph and this general motion with a decrease in forward speed is expected within the next couple of days. Computer models are in good agreement and they, as well as the official forecast from the National Hurricane Center, take Leslie northeast of the Leeward Islands through the weekend with a turn toward the north next week.

Florida outlook:
·         No part of Florida is within the 5 day error cone of either Hurricane Kirk or Tropical Storm Leslie and neither storm is forecast to directly impact the Sunshine State. 
·         Scattered showers and thunderstorms are in the forecast for North Florida through the weekend and an additional 1 to 3 inches of rain is expected over the area. More isolated showers are expected over the Peninsula and rainfall amounts will likely be near half of an inch or less.
·         Lingering ocean swells and large waves up to 3-6 feet along the Western Panhandle coast today will result in a high risk of rip currents. A high rip current risk is also in place for the beaches of West Central Florida today as ocean swells from Isaac continue to impact the western coast of the Florida Peninsula.
·         A High Surf Advisory has been issued for Escambia, Santa Rosa and Okaloosa Counties until noon today and a Rip Current Statement is in place for Pinellas County through Lee County through this evening.
