Over the past couple of days we've been working on an easy-to-understand indicator of the risk of wind-driven dust clouds in and around Christchurch city. To our knowledge, no-one’s tried this before.
These 'dust graphs' are now live on metservice.com so that the people of Christchurch, emergency services, lifelines and others have more information to help them deal with the very trying circumstances they continue to face.

Robert FitzRoy is famous as captain of the Beagle on the voyage when Darwin made his discoveries, although many New Zealanders also know FitzRoy as Governor of New Zealand before George Grey. But to meteorologists, FitzRoy is famous as one of the pioneers of weather forecasting; indeed, FitzRoy coined the term "weather forecasting". He was also a superb navigator and surveyor whose charts of South America were still in use more than 100 years after he made them.
We're well aware of the concerns about dust being blown around during a period of stronger winds expected in the Christchurch area from later Tuesday to later Wednesday.
As of the time of publishing this blog (3:00pm Monday 28 February 2011), there's a Severe Weather Warning in effect for severe gales in inland areas of Canterbury and the higher parts of Banks Peninsula, but not for Christchurch. The Warning has been issued well in advance of the severe gales: they are expected on Tuesday night and Wednesday morning.
This is the last post in this series of forecasts for Christchurch. The forecast team are paying extra special attention to the Christchurch forecast and today we've added high resolution radar imagery to metservice.com. We're also putting considerable effort into providing forecast support to those involved in the emergency response.
