Overall Orange alert Tropical Cyclone for FRANKLIN-17

Storm surge for tropical cyclone FRANKLIN-17

Green alert for storm surge impact in Mexico

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 15 of tropical cyclone FRANKLIN-17 issued at 10 Aug 2017 9:00:00 (GDACS Event ID 1000383).


Current impact estimate:

  • Population affected by cyclone-strength winds (>120km/h): 1.1 million
  • Saffir-Simpson Category: Category 1
  • Maximum sustained wind speed: 139 km/h
  • The maximum Storm surge height is  0.7m in Santa Cruz, Mexico. This height is estimated for 09 Aug 2017 03:00:00.

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.
