The wild weather is not over yet, as the Met Office warns of gales and downpours , combined with huge surf on Wednesday, and even bigger waves on Saturday.
The "largest waves" ever headlines refer to the size of Wednesday's expected swell, which is forecast to be 28feet at 18 seconds at Wednesday's high tide (8.10am). The wind will be a roaring 40+ mph from the S/SW.
Tides will be high, within the spring tide range, but not as high as recent days, which may be the bar's saviour.
While huge, these are not the biggest waves ever to have hit Cornwall, rather this is set to be the biggest nearshore swell size anywhere in the world on that date.
The thunderous waves are set to return on Saturday, with the forecast for and even bigger inshore swell of 29.5 feet at 19 seconds.
In terms of weather, another spell of wet and windy weather is set to cross the county from the west today, with outbreaks of heavy rain accompanied by strengthening southerly winds.
These combining with high tides mean the risk of coastal flooding in exposed locations remains.
The public should be aware of the risk of further disruption.
Heavy rain and very strong winds will move northwards across the UK from Tuesday evening onwards through much of Wednesday. This could bring widespread rainfall accumulations of 20-30 mm across many southern and some central parts, with an excess of 40 mm in some spots.
Accompanying this, very strong winds are likely with gusts of 60-70 mph likely, mainly along exposed coasts, and perhaps even 80 mph along some coastlines in the southwest.
The 'Yellow Warning' says: "The public should be aware of the risk of disruption from flooding given the rain falling onto saturated ground. Strong winds may cause some damage, with disruption due to fallen trees particularly likely. With large waves and high tides, there is a further risk of flooding in some coastal areas.
The foul weather is due to a low pressure system developing in the Western Atlantic on Monday, deepening rapidly before moving northeast across the UK late on Tuesday through Wednesday.
Another 20 mm of rain, perhaps with 30 mm or more locally in Cornwall, is likely, much of it within 3 hours or so. Whilst totals will be less (5-10 mm) further east, pre-existing saturation brings the risk of flooding here too.
Winds will also strengthen to give gusts of 50 to 60 mph around exposed coasts and headlands. Gales coupled with high tides brings the risk of waves overtopping coastlines.
Impacts are expected to be more severe on the South Coast compared to recent days. Overtopping of coastal defences is likely with high energy large waves and spray, combined with high spring tides and strong south to south easterly winds. Beaches, coastal promenades, roads and footpaths will be extremely dangerous.
Wind is forecast to be force 8 to 9, with a tidal surge of around 400 mm. The recent storms have caused damage at coastal locations. There may be an increased risk at Stonehouse, Plympton, Lamorna, Penzance, Porthleven, Mullion, Pentewan, Seaton and Kingsand. Coastal areas will be extremely dangerous, people are advised to avoid these areas.
