Discussion: Strong north-westerly winds (50-60km/h gusting 70km/h) can be expected over southern Namakwa and central and eastern interior of the Western Cape during the afternoons of Monday and Tuesday, although excluding the Garden Route for Tuesday. North-westerly to westerly winds are also expected to reach gale force (60-70km/h gusting to 80km/h) between Cape Columbine and Cape Agulhas from Monday night, spreading to Still Bay on Tuesday afternoon moderating the evening.

Impact: Localised damage to settlements can be expected. Localised problems can be expected for high-sided vehicles on prone routes (N1, N7, R321, R43). Risk for spread of runaway fires (new and existing). Over the coastal areas, localised disruption of small harbours or ports for a short period can be expected. Difficulty in navigation at sea due to strong winds and choppy seas may lead to small vessels being at risk of taking on water/ capsizing.

Instruction: Be aware of the following: sudden cross winds if travelling especially between buildings, fallen trees or power lines. Ensure that all temporary structures are well anchored. Small boats must stay away from the open sea and seek the shelter of a harbour, river estuary or protected bay.
