Tropical Cyclone Ita made landfall with 10-minute average sustained winds around 105 mph between 9 and 10 p.m. local time, according to the Australia Bureau of Meteorology. This would equate to a Category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale, after adjusting this wind speed to an equivalent one-minute sustained wind used as a standard in the U.S.

Cape Flattery measured a peak wind gust just shy of 99 mph at 9 p.m. local time Friday, and had already picked up over three inches of rain from Ita's outer rainbands and eyewall before observations ceased there around 10 p.m.

According to the Cairns Post, roof damage was reported to the James Cook Museum in Cooktown, as well as to several homes in the town. The peak wind gust clocked, there, was 76 mph.

Heavy rain and flooding is possible over parts of northeast Australia into Sunday as the center of the cyclone turns southeastward and heads back into ocean. 

Tropical cyclones are not uncommon in Australia. The Australia Bureau of Meteorology says that the season typically runs from November through April.

In fact, this part of northeast Australia is thought to hold the world record for highest storm surge from the 1899 Bathurst Bay Cyclone.

The northwest coast of Australia has the most frequent encounters with tropical cyclones and averages about two landfalls each season. Intense Category 4 or Category 5 cyclones are most likely to occur in March and April.

Prior to heading towards Australia, Ita and the disturbed area of weather it formed from produced heavy rain and deadly flooding in the Solomon Islands

Ita then rapidly intensified from a strong Category 1 to a Category 4 equivalent cyclone in just 12 hours Thursday.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
