The map I generate of Iceland with mkgmap and --genarate-sea and
--remove-short-arcs got flooded between 25th ond 26th October.
If I just use the --generate-sea option the map is not
--remove-short-arcs I get a lot of RoadNetwork warnings but the map is
not flooded.
Here are the two .osm files:

osmdiff report between the two:

To reproduce this on the latest file just do:
wget http://osm.nix.is/latest/Iceland.osm.bz2
bzip2 -d Iceland.osm.bz2
# Generates flooded map
mkgmap --generate-sea --remove-short-arcs Iceland.osm
# Map is not flooded
mkgmap --generate-sea Iceland.osm
