Tropical Cyclone


Tropical Cyclone Narelle, currently situated around 300-400km off of the Northern Coast of Western Australia has recently been downgraded to a category three storm (at one point it ticked all the criteria for a category 5 storm). The Bureau of Meteorology believes that Narelle is unlikely to make landfall, but they are closely tracking its progress just in case it does change direction and move closer to the coast.

On January 11th 2013, NASA’s MODIS (Moderate Resolution Imaging Spectroradiometer) captured the below image of the storm. In the image the eye of the storm has clearly been formed, with imagery showing the size of the eye to be of 27km wide. As well as measuring the size of the eye of the storm and capturing some pretty amazing images of Narelle, NASA satellites have also been able to tell the amount of rainfall occurring within the storm. TRMM (Tropical Rainfall Measuring Mission) recorded a rainfall of 50mm per hour at its highest point on Januray 11th 2013.
