Abstract -- The very short-range forecast system in the Central Weather Bureau (CWB) comprises three sub-systems: (1) Warning Decision Support System (WDSS), (2) Quantitative Precipitation Estimation-Segregation Using Multiple Sensors (QPE-SUMS) and (3) Local Analysis and Prediction System (LAPS) MM5 hot-start. With System (LAPS) MM5 hot-start. With the WSR-88D data the WDSS, developed by the National Severe Storm Laboratory (NSSL), is able to detect and track the storm-scale systems. Severe storm algorithms to detect hails, tornadoes, bounded weak echo regions, etc. reside in the WDSS. The WDSS is operational in the forecast center of the CWB. The second generation of the WDSS with multiple radar data processing capability is to be installed in the CWB. The QPE-SUMS, designed by the NSSL, is able to make convective/stratiform rainfall estimates based on the mosaic of the Doppler radar network. A prototype of the QPE-SUMS was installed in the CWB. The QPE-SUMS related products are to be on the WINS as one part of the forecaster aids. Some quality control processes of the radar data, which may significantly affect the quality of QPE-SUMS are still under way. The LAPS MM5 hot-start module with advanced cloud analysis scheme is going to be installed in the CWB to improve the first 12-hour model forecast.
