StormSurge

1.1 m

The maximum Storm surge height is  1.1m in Sunharon Roads, Northern Mariana Islands. This height is estimated for 24 Oct 2018 15:00 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 (16 locations). Calculation based on advisory number 15 of 25 Oct 2018 00:00:00 UTC. (Simulation using 6 minute resolution)
