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.

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.
