My Grandparents had a saying about weather:
Weather
Whether the weather be fine
Or whether the weather be not
Whether the weather be cold
Or whether the weather be hot
We'll weather the weather
Whatever the weather
Whether we like it or not.
Not so on a (fishing) kayak.
Yesterday was a sunny day in Brisbane/Moreton Bay, with light winds. Redcliffe/Scarby area attracted quite a few kayak fishos, in near perfect conditions.

Hey, you don't often get better conditions than that!
The light winds continued into the afternoon. A few clouds formed around 1.00 pm in the west, but the lads were all probably out by then, because there was hardly a scale between them. If they weren't out by then, they should have been, cause one of those clouds now looked like this

It hit the Redcliffe area at 2.06 pm. Notice that at 2.00 pm, the winds were light. The storm affected all of northern Moreton Bay, whipping up dangerous winds everywhere within minutes, albeit from an almost calm sea. While there was no precipitation at Redcliffe, look carefully at the wind speed.

At 27 - 33 knots many yakkers would be off their kayaks, with a high probability of being separated from their kayak, aka as flotsam, in what would have been huge seas within minutes.
The affected area was approximately 45 X 45km. You cannot hide from storms. Don't even try.
A storm in Australia can contain rising air to a height of 60,000 '. They are amongst the severest in the world. Within the thunderstorm cell there are very high speed winds, shearing in relation to each other, and at sea level, these winds can extend a long way outside of the cell (where the precipitation occurs).
These horizontal winds can be so severe at sea level to flip a light aircraft, resulting in a crash. VFR pilots are advised to stay over 20 nautical miles (38 km) from a storm cell, and even large commercial aircraft all carry weather radar, specifically to avoid the massive windshear that often occurs in storm cells at the surface (for further reading, look up 'microbursts').
The moral of the story is...... Don't mess with storms in a kayak.
Stay safe
