That's... a rather large storm surge, especially to have made it this far up the creek. Remember, to reach Fareham proper the tide has to pass through the gap between Gosport and Portsmouth before spreading out into Fareham lake. The answerphone message additionally warned that "flooding is expected 2 hours before high tide". Now, I do live on the first floor so the chances of me getting flooded by the sea are tiny (the last floods didn't even reach the bottom of the steps to the front door) so I'm not overly worried, but still that's quite the storm.
Batten down the hatches, folks.
