Green alert for storm surge impact based on GFS source

The JRC has developed an experimental global storm surge model, which is run after each advisory issued by the regional tropical cyclone centres. The calculations are published about 20 minutes after a new advisory is detected by GDACS. The calculations identify the populated places affected by storm surge up to three days in advance, using the forecasted track. When forecasts change, the associated storm surge changes too and alert levels may go up or down.

This report is for advisory number 5 of tropical cyclone LINDA-18 issued at 13 Mar 2018 12:00:00 (GDACS Event ID 1000440). However, the calculation for advisory number is not completed. Therefore, the latest available calculation is shown. All links, data, statistics and maps refer to the latest available calculation.

More information

The atmospheric forcing included in the storm surge model are the pressure drop and the wind-water friction. The effects of the short waves induced by the wind (wave setup) and the precipitations are not yet implemented in the model.
