Application of free meteorological information on the Internet WWW to landslide disaster warnings, especially application of short term rain forecasts based on radar rain gauges, is a solution to appropriate warning and evacuation system. However, this information doesn't have enough accuracy in some cases. Hence, in this study, its reliability is examined with observed rain data, taking meteorological types into account. Eventually, following results are revealed. 1) The stronger the precipitation is, the less precise the information of short term forecast is. 2) Meteorological types have considerable effect on the accuracy of the information of short term forecast. The accuracy tends to reduce with the meteorological type related to approaching low pressure. Notwithstanding this tendency, it doesn't reduce in case of typhoon. 3) It is noteworthy that in strong rainfalls the short term rain forecast tends to give underestimated values.
