GDACS is a cooperation framework between the United Nations, the European Commission and disaster managers worldwide to improve alerts, information exchange and coordination in the first phase after major sudden-onset disasters.

Overall Green alert Tropical Cyclone for NATE-17

Storm surge for tropical cyclone NATE-17

Orange alert for storm surge impact in United States

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 NATE-17 issued at 8 Oct 2017 15:00:00 (GDACS Event ID 1000408). 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.


Current impact estimate:

  • Population affected by cyclone-strength winds (>120km/h): No people affected
  • Saffir-Simpson Category: Category 1
  • Maximum sustained wind speed: 148 km/h
  • The maximum Storm surge height is  1.9m in Gulf Park Estates, United States. This height is estimated for 08 Oct 2017 08:00:00.

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.
