Using Toshiba's proprietary technology, we can analyze rain cloud development process in real-time based on weather radar data, and predict localized heavy rain ("guerrilla rainstorms") and the amount of precipitation accurately up to 30 minutes ahead.

Localized heavy rainfall, also known as "guerrilla rainstorms" in Japan, may occur suddenly and bring significant precipitation. They are difficult to predict and likely to cause various types of damages.

Toshiba's "Rainfall Prediction Service" can provide rainfall prediction information before roads become flooded, rivers overflow, landslides occur, and basements and buildings become flooded. It can be used to respond to different scenarios, such as closing underpasses and controlling traffic signals during disasters, deciding how various transportation services will be operated, issuing evacuation orders in dangerous areas directing people to safe places, and taking measures when holding outdoor events.
