Cabo Verde to Experience Strong winds and heavy rain in next 24 hours

Last night I was uncertain about the model forecasts but this morning I feel confident that Cabo Verde will experience heavy rain over the next 24 hours (https://distilleryafrdiaspora.blogspot.com/2020/08/data-void-west-africa-makes-tropical.html). The question is how much will this system develop before impacting the country.  

It is moving fairly fast and so may pass over quickly.  The forecast model guidance is not so clear about this but yesterday's 12 Z model run had the center of the disturbance passing very close to Praia.  Yesterday's forecast suggested a center would form off the coast of Senegal and it did.    This forecast shows that area of low pressure and surface winds in the 30-35 knot (55-65 kph) range will pass near Praia tomorrow morning.

The 8 AM advisory states that strong winds and heavy rain are likely.  

The WRF forecast from yesterday suggests rain will be heaviest in the southern portions of Cabo Verde.

However, this model always underestimates rainfall so this is just guidance.  

Thoughts 

If you live in the southern Islands of Cabo Verde including Brava, Fogo, and Santiago (including the capital, Praia):

1. be very careful on the roads over the next 24 hours for flooding. 

2. secure any items that strong winds might blow over

3.  Pay attention to your local TV about changing conditions or messages from Civil authorities.

I will post new forecasts over the next few hours.
