Akshay Deoras

As had earlier been said,cyclone ului is heading straight towards Australia's North Eastern part. AS per the latest observations this cyclone will make a landfall somewhere between Bowan and Mackey,Queensland and the eyewall is expected to pass through Proserpine. TC Ului has devastating wind speed ranging to 63mph gusting to 64mph. Ului is at present 19.9 S and 151.7E. Ului, currently a category two storm on the scale of one to five, is 365 kilometers (227 miles) east-northeast of the city of Mackay, moving west southwest at 27 kilometers an hour, Australia’s Bureau of Meteorology said on its Web site in a bulletin issued at 1:55 p.m. local time. The state government preemptively declared a disaster situation.T

This cyclone is expected to strengthen as it comes to the coast. Recently it had weakened due to a NW WIND SHEAR.But recent satellite images are showing that it has strengthen to some extent leading to high wind. The difference in the two 6hourly images is showing that the cyclone has organized a lot. According to Australian meterology this cyclone will be cat 3 at the time of landfall.
here is the bulletin----

The cyclone is expected to cross the coast between Ayr and Mackay, most likely in the Proserpine region as a severe tropical cyclone early Sunday. The cyclone is then expected to weaken inland later on Sunday.

VERY DESTRUCTIVE wind gusts to 200 km/hr near the cyclone centre may affect coastal and island communities in the threatened area late tonight and early Sunday.

DAMAGING winds are expected to develop between Cardwell and Yeppoon this evening, then extend to adjacent inland parts during Sunday.

TIDES between Bowen and St Lawrence may rise to just above the highest tide of the year overnight with very rough seas and dangerous conditions along the foreshore.

HEAVY RAINFALL and flooding are likely to develop about coastal and adjacent
inland areas between Bowen and St Lawrence early Sunday.

DANGEROUS SURF conditions are expected to continue about exposed beaches south
of the cyclone until later on Sunday. A separate Severe Weather Warning is
current for these conditions.

People in the path of the dangerous cyclone should stay calm and remain in a secure shelter while the very destructive winds develop late tonight and early Sunday. Do not venture outside if you find yourself in the eye of the cyclone as winds may remain light for up to an hour - very destructive winds from a different direction could resume at any time. Heed the advice and follow the instructions of Police or State Emergency Service personnel.
