1-3 Seasonal Rain Front and Typhoon Caused Heavy Rains in  Kyushu and Tohoku
area, Japan
Japan Meteorological Agency has issued  heavy rain warnings / advisories to
Kyushu and Tohoku area.
Heavy rain has already caused a man missing in Kagoshima prefecture of
Kyushu region.
In Tohoku area, affected by Great East Japan Earthquake, inundation damage
is a serious concern due to the land subsidence after the  earthquake, and
landslides are worried to occur especially in the unstable hillside areas.

3. Information from the IFNet secretariat
IDI-Japan has been developing Global Flood Alert System (GFAS) since 2006.
The GFAS takes rainfall observation data from multiple observation
satellites (as provided by NASA, USA) and provides the information in
graphical form with heavy rain notice based on probability estimate, which
supports flood forecast.
Originally, GFAS was developed by using TRMM-3B42RT rainfall data.
Recently, JAXA has developed a new algorithm of satellite rainfall data,
which is called "GSMaP".
In line with it, GFAS has been improved to utilize GSMap, which enable to
shorten the latency of rainfall data delivery and  provide smaller scale
mesh data.

After the improvement of the new GFAS, we have added rainfall maps of about
60 countries and river basin maps.

We are waiting for your participation on this project and opinions/comments
about GFAS.

IFNet is an open network, purpose of the activities is to share experiences
and information on flood issues.
We look forward to your active participation and flood related information
to be shared among participants.
