Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

AUSTRALIA: TC Hamish Moving South

Posted by feww on March 9, 2009

Australian Bureau of Meteorology predicts TC Hamish will remain a Category 4 system Monday night as it hovers near shoreline along the central Queensland coast.

Hamish, downgraded to a category 4 storm, is located near the Capricornia coast about 250 km east of Yeppoon and 240 km north-north-east of Bundaberg, moving south south-east at near 16 km per hour, a report said.

Powerful winds could cause substantial damage to townships and  communities between Yeppoon and Hervey Bay. Australia’s Bureau of Meteorology expected sea levels to rise above normal tide line as Hamish moves south-east. Minor flooding may occur along the shoreline.

Hamish is expected to weaken further in the next 24 hours.

With winds near 240 kilometers per hour (150 miles per hour or 130 knots), Tropical Cyclone Hamish was a powerful Category 4 storm (on the Saffir-Simpson Scale) as it moved down the northeast coast of Australia on March 7, 2009. The storm formed on March 5 off the Queensland coast, and intensified as it moved southeast just off shore. By the time the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on the morning of March 7, the storm was well-formed. The intense storm has a distinct eye, surrounded by a wall of towering clouds. As of March 7, the Joint Typhoon Warning Center predicted that Hamish would come ashore just north of Brisbane on March 9. The storm was forecast to weaken before making landfall.

The forecast path shown above is the Bureau’s best estimate of the cyclone’s future movement and intensity. There is always some uncertainty associated with tropical cyclone forecasting and the grey zone indicates the range of likely tracks.

Due to the uncertainty in the future movement, the indicated winds will almost certainly extend to regions outside the rings on this map. The extent of the warning & watch zones reflects this. (Australia’s BoM)

Remarks:

Severe Tropical Cyclone Hamish is expected to maintain a southeast track parallel to the coast overnight, before slowing down and beginning to weaken during Tuesday.

Damaging winds are expected to continue to affect offshore islands between Yeppoon and Double Island Point (including Heron Island, Lady Elliot Island, and Fraser Island) during the next 24 hours.

Damaging winds are not expected to develop about the mainland coast between Yeppoon and Double Island Point during the next 24 hours, however they may develop later.

As the cyclone moves to the southeast, sea levels are expected to be elevated above the normal tide along the coastline and large waves may produce minor flooding along the foreshore. People living in areas likely to be affected by this flooding should take measures to protect their property as much as possible and be prepared to help their neighbours.

People on offshore islands between Yeppoon and Double Island Point (including Heron Island, Lady Elliot Island, and Fraser Island) should immediately commence or continue preparations, especially securing boats and property.

People on the mainland coast between Yeppoon and Tewantin should consider what action they will need to take if the cyclone threat increases. If you are unsure about the actions to be taken, information is available from your local government or local State Emergency Service. (Source: Australia’s BoM)
