10 July 2020 Severe Weather Alert: Damaging Winds

The Cape Town Weather Office has issued the following severe weather alerts.

Hazard: Damaging Winds

Alert level: Warning

Valid From (SAST): 10/07/20 01h00

Valid To (SAST): 11/07/20 18h00

  1. Strong interior westerly to north-westerly winds (50-62km/h) are expected over the Namakwa District (N.Cape) as well as the Central Karoo (W.Cape) today.
  2. Gale to strong gale force south-westerly winds (70-100km/h) along the coastal areas between Lambert’s Bay and Plettenberg Bay on Saturday (11/07/2020) morning, moderating by the afternoon.


Strong damaging winds often occur along coastal regions, but also often occur during thunderstorm activity. These winds are sudden and can cause much damage.


Stay indoors where possible away from the windows that open towards the severe winds. Be aware of the following: – sudden cross winds if traveling especially between buildings, fallen trees or power lines and flying debris.

Small boats must stay away from the open sea and seek the shelter of a harbour, river estuary or protected bay.

Parked aircraft should be pointed into the direction of the wind and secured Listen to the radio or TV for warnings and obey the instructions from disaster management officers.


Snow is precipitation in the form of flakes of crystalline water ice that fall from clouds. Since snow is composed of small ice particles, it is a granular material.


If driving decrease your speed and leave yourself plenty of room to stop, you should allow at least three times more space than usual between you and the car in front of you. Brake gently to avoid skidding. If your wheels start to lock up, ease off the brake. Even at temperatures above freezing, if the conditions are wet, you might encounter ice in shady areas or on exposed roadways like bridges. Listen to the radio or TV for warnings and obey the instructions from disaster management officers.


Flooding occurs when water overflows its normal channels such as streams and storm water drains. It can occur with prolonged period of rain, with continuous heavy falls or in the form of flash floods which are usually associated with severe thunderstorms. Heavy rain may also result in river flooding causing damage downstream to areas that may receive no rainfall at all during the flooding event.


If possible stay indoors and off the roads, avoid crossing rivers and swollen streams where water is above your ankles. If trapped in flooding in a vehicle, abandon it and climb to higher ground. In buildings, move valuables to a safe place above the expected flood level. Switch off electricity at the supply point to the building. In rural areas protect/relocate animals to a safe place on higher ground. Abandon your home immediately if evacuation is recommended, before access is cut off by flood water. NEVER drive on a road covered by water. You do not know how deep it is or if the road has been washed away. If the vehicle stalls, leave it immediately and seek higher ground. Be especially cautious at night when it’s harder to recognize flood dangers. Listen to the radio or TV for warnings and obey the instructions from disaster management officers.
