Notes

Strong flow straight out to sea & also to east

Water being drawn out of estuary causing large waves to go upstream along channel (channel has steep sides -to .70m. high) , these waves start near the tunnel entrance in an area that has a large shallow water covered sand build up

Water extremely turbid, sand swirls everywhere & long 'drag' lines are across sand where water has been drawn off

Mouth wide, rough seas causing waves to surge over top of rocks

East end of beach still being impacted by SW waves which have created a sheer sand cliff about 1-2m. high

Very strong longshore drift & rip

Strong flow downstream at G2 but waves also coming upstream toward bridge

All areas remain flooded. OOR .80m. near flood markers @ 08:45
channel near boardwalk (also over boardwalk) where algae is starting to form
Several Portuguese Man o' war along swash line on beach

2 large tiger snakes near G2 bridge
