I have heard word that the Bureau of Meteorology have been telling media outlets that the Willis Island obs station has been badly damaged or destroyed. No observations for the past 40mins they are reporting.

I have heard word that the Bureau of Meteorology have been telling media outlets that the Willis Island obs station has been badly damaged or destroyed. No observations for the past 40mins they are reporting.

Almost an hour since the last obs and radar is also delayed. I won't be surprised if it's either destroyed or damaged.

Yes Rod, it appears that the radar has been taken out at Willis Island. I suspect the instruments recording windspeed may have been "over maximum range" for about half an hour , but are now recording correctly again. I guess we will see in the next hour or so.

the cyclone was likely to hit earlier than expected around 10pm (AEST)

QUEENSLAND Premier Anna Bligh says north Queenslanders at risk of tidal storm surges have very limited time to evacuate as Cyclone Yasi nears the coast as a category five.

The Bureau of Meteorology (BoM) in Brisbane said that at 4am AEST Yasi was about 650 kilometres east-northeast of Cairns and 650 kilometres northeast of Townsville moving west southwest at 30km/h.
"The cyclone has now reached category five and will continue to move in a west-southwesterly direction during today," the BoM said on its website this morning, as it upgraded its forecast from high category four.
Coastal residents, particularly between Port Douglas and Townsville, were being warned of an "extremely dangerous" storm tide as the cyclone approaches and crosses the coast. It is likely to cause flooding some way inland.
Winds with gusts to 90km/h were expected on coastal islands later on Wednesday morning, then extend on to the coast during the day.
Gusts over 125km/h were expected between Cooktown and Ingham in the afternoon, and gusts reaching above 280km/h between Port Douglas and Cardwell in the evening as the cyclone approached.
Ms Bligh told Sky News evacuations of low-lying areas were still taking place.
She said the cyclone was likely to hit earlier than expected around 10pm (AEST) at high tide.
"That means storm surges are an even greater problem today than we have contemplated yesterday.
"People still have a very small window of opportunity to move to a safer place."
She said they should relocate to homes of family and friends that are not at risk of the tidal surges.

yeah and now back down to 937.6 so still in the eye for sure

[Rod Hagen]

That means that the eye is taking more than an hour and twenty minutes to pass over. If it is still that size when it reaches the coast it suggests the eyewall is going to hit a pretty wide swathe of country!

"Yasi knocks out weather radar
By Kim Lyell

The weather bureau's radar and wind speed measurements on the island failed just before 9am (AEST).

The bureau says the maximum wind speed recorded before the equipment went down was 185 kilometres an hour.

Three weather observers and a technician left the island yesterday."
