NASA's IMERG Shows Cindy's Extreme Rainfall

Tropical storm Cindy was downgraded to a tropical depression after moving onshore near the Texas and Louisiana Border on Thursday June 22, 2017. Flooding was reported along the the Gulf Coast even before Cindy made landfall. The rainfall around tropical storm Cindy was asymmetrical. The majority of heavy rainfall with the tropical cyclone was located east of Cindy's center in the states along the Gulf Coast from Louisiana through the Florida Panhandle. The tropical depression continued to spread heavy rain and occasionally severe thunderstorms after it came ashore.

Bangladesh's Heavy Rainfall Examined With IMERG

At least 156 people in Bangladesh were killed during the past week by landslides and floods caused by heavy rainfall. Monsoon rainfall has been especially heavy over this area that includes southeastern Bangladesh, northeastern India and western Burma (Myanmar). This disaster follows quickly on the heels of deadly cyclone Mora which hit the same area a couple weeks ago.

IMERG Shows Heavy Rainfall From Southwest India To Northeast India

In the past couple weeks rainfall has had a significant impact on Sri Lanka, southwestern India, Bangladesh and eastern India. Monsoon rainfall caused widespread flooding, devastating mudslides and displacements of many thousands of people in Sri Lanka. Over 200 people's deaths have now been attributed to this disaster. Then cyclone Mora formed in the Bay Of Bengal on May 27, 2017. Heavy rain from Mora and it's remnants moved over southeastern Bangladesh and northeastern India. Monsoon rainfall also started to move into southern India.

IMERG Sees Record Australia Rainfall

Over the past week extreme rainfall has drenched northeastern Australia. This is the heaviest rainfall in that area since tropical cyclone Debbie hit Queensland Australia in late March. Much of the recent extremely heavy rainfall was due to storms associated with a trough of low pressure slowly moving over northeastern Queensland from the Coral Sea. More than 100mm (3.9 inches) of rain in 24 hours was reported near Townsville in northern Queensland. A trough of low pressure moving eastward from central Australia has also been encroaching into western Queensland.

Heavy rainfall has recently caused widespread flooding and landslides in Jamaica. Occasional showers from trade winds are normal in Jamaica but recent rainfall from slow moving troughs have been unusually heavy. A 1009 mb low pressure center located in the western Caribbean was disrupting the normal trade winds over Jamaica today. 

V04 Reprocessed Early and Late IMERG products

The GPM project has reprocessed all the original NRT IMERG data both EARLY and LATE to product version V04A.  In addition, this reprocessing brought the IMERG  dataset back to the beginning of the GPM mission in March 2014.  The original NRT IMERG started its processing in March of 2015.

Currently only the HDF5 products have been reprocessed to V04A.  The TIFF/TFW versions will also be reprocessed but this will take a while longer.
