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 17 of tropical cyclone DEBBY-12 issued at 27 Jun 2012 15:00:00 (GDACS Event ID 30970). 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.
Summary
Current impact estimate:
- Population affected by cyclone-strength winds (>120km/h): No people affected

- Maximum sustained wind speed: 93 km/h
-
The maximum Storm surge height is
2.3m
in Skipper,
. This
height is estimated for 25 Jun 2012 23:00:00.

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.
The model has been validated mainly in areas of shallow water (Caribbean, Bay of Bengal). Results in other basins may be inaccurate.
