Hurricane update - 15 August

Tropical storm Ana has formed in the Atlantic Ocean, 1,000 miles east of the Leeward Islands. This system will move west at a speed of 16 mph, and will gradually gain strength. Its course will veer from due west (at present) to west northwest, taking it past Puerto Rico, Hispaniola and the Bahamas towards Florida. The latter section of the forecast track is full of uncertainty, and close monitoring of the NHC output (every 6 hours) is required if you are at all concerned.

The Pacific currently shows two cyclones, a weak tropical depression called Maka, which has drifted across from the Central Pacific - it formed southwest of Hawaii 4 days ago. The second system is category III hurricane Guillermo, which is located 1,450 miles west of Baja California and is heading west northwest, towards the sea area north of Hawaii.
