Freak January 2011 continues — cyclone coming our way

FINAL UPDATE: The far southwest cyclone is just… drizzle. Best wishes for the Queenslanders who are dealing with the real thing right now.

UPDATE#3: Sunday morning –The Cyclone is now Category 1, and wind speeds only 100km/hr and falling, so the BOM have turned off the CYCLONE Alert, and now call it a “Low”. Their map suggests whatever’s left will have a direct hit on perth, but the infra red image suggests it’s already gone past… and will just clip the lower corner of the state.   Looks like it will just be a stormy day.

UPDATE #2: Saturday night –This glorious NASA image shows Bianca a few days ago. Right now the cyclone is losing strength over the cooler water as it heads towards the West Australian Southern coast. Windspeeds have dropped from 185km/hr to 140km/hr. But I thought the intricate detail in this photo was magnificent.

Cyclone Bianca tracks towards SW Western Australia. (Click on the image to go to the BOM page to watch the hourly updates of satelite images.)

Hurricanes, storms take holiday too

Will a hotter world lead to more intense storms?

2010 might be on track to be the warmest ever (according to GISS), but right now, we may be about to set a new record of tropical storms — in inactivity. Ryan Maue tracks the global accumulated activity and reports that by the end of July we might break the record low we set last year.

Ryan N. Maue’s 2010 Global Tropical Cyclone Activity Update

July 15: If no additional ACE occurred in July, the 24-month global ACE total would be 1095 compared to last month at 1173. The previous 30-year low was 1091 set recently in September 2009. No lower values exist during the past 30-years.

Global and Northern Hemsiphere Tropical Cyclone Activity is near a record low

Looking at the National Hurricane Centre, it doesn’t seem like there is much activity on the way between now and the end of July.

Advisories issued for the North Atlantic, The East Pacific, The West Pacific, and the Indian Ocean are all the same:

There is no tropical storm activity for this region.
