TROPICAL STORM NANA IN THE AREA
The Cayman Islands National Weather Service(CINWS) has advised that heavy rainfall is possible beginning later this afternoon which could lead to flooding of low lying areas as newly-formed Tropical Storm Nana passes through the Western Caribbean.
The storm is expected to pass south of the Cayman Islands but the Cayman Islands National Weather Service(CINWS) and Hazard Management Cayman Islands(HMCI) say there remains some uncertainty in the forecast track.
The US National Hurricane Centre(NHC) currently puts the probability that Grand Cayman will experience tropical storm force winds at between 10 and 20 per cent, and the Sister Islands at between 5 and 10 per cent.
The disturbance located south of Jamaica has rapidly strengthened into Tropical Storm Nana and is moving west at 16 mph with maximum sustained winds of 50 mph.
Some continued strengthening is expected. Tropical storm force winds extend out up to 80 miles from the centre of circulation, mainly on the north side of the storm.
The CINWS forecast for today is for partly cloudy skies with a 30% chance of showers this morning, becoming cloudy with a 60% chance of showers and some thunder by this afternoon. Showers may become locally heavy at times.
Winds are east to north-east at 10 to 15 knots with higher gusts and the sea state is slight with wave heights of 1 to 3 feet.
Some deterioration of conditions is expected Wednesday with cloudy skies and an 80% chance of showers and thunder.
Winds will shift to easterly at 10 to 15 knots with higher gusts while the seas will be slight to moderate with wave heights of 2 to 4 feet.
However, the CINWS advises that seas may become choppy in and around heavy showers.
