StormSurge

0.3 m

The maximum Storm surge height is 0.3m in La Roche Godon, French Southern and Antarctic Lands. This height is estimated for 04 Feb 2024 16:00 UTC .

The JRC has developed an experimental global storm surge model. 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. All links, data, statistics and maps refer to the latest available calculation. If the calculation for the last advisory is not completed, the latest available calculation is shown.

Locations affected by Storm surge (1 locations). Calculation based on advisory number 11 of 02 Feb 2024 06:00:00 UTC. (Simulation using 6 minute resolution)

Alert	Date (UTC)	Name	Country	Storm surge height (m)
	04 Feb 2024 16:00	La Roche Godon	French Southern and Antarctic Lands	0.3
