Hurricane update - 22 August

Three systems that need to be monitored very closely.

Typhoon TEMBIN is carrying winds of 105 mph as it heads for central Taiwan. The storm will bring these winds, alongside very heavy rainfall to the island state late tomorrow local time. Three counties are under warning; this number is likely to increase. Taiwan Weather will carry further updates on these. The Joint Typhoon Warning Center in Honolulu is issuing 6-hourly warnings. In the longer term, Tembin will probably head southwest along the east coast of China, bringing copious amounts of rain to areas that have seen several typhoons already this year.

Tropical storm ISAAC is headed for the Lesser Antilles and will intensify to hurricane strength on Friday. The storm will clip the island of Hispaniola, pass over Cuba and reintensify in the Florida Straits to make landfall in southern Florida at 80 knots (95 mph) in the early hours of next Monday. At five days' notice, this forecast carries a large margin of error. The National Hurricane Center in Miami is issuing 3-hourly advisories.

Tropical disturbance 96L will probably be declared depression 10L later today as it travels west past the 35th degree longitude in the central Atlantic Ocean. Like Isaac, 10L will be a Cape Verde cyclone.
