The destruction due to storm surge flooding is a serious concern along the coastal regions of the countries around the North Indian Ocean. Thus, provision of precise prediction and warning of storm surges is of great interest in the region. IMD uses the Nomograms and IIT-Delhi model for location specific storm surge prediction. The model predicts surges with reasonable accuracy. IMD needs to improve both storm surge model as well as meso-scale NWP model to further enhance storm surge forecasting capability in the region. Present technique predicting only residual storm surge requires improvement in order to forecast total water level envelope (TWLE) occurring as a result of the combined effect of the interaction of storm surge with tides, wind waves, and several other factors.
