Is getting cloudy and rainy lately. I guess wet weather in Malaysia and Cameron Highlands is to be expected. It is now the middle of the south-west Sumatran monsoon season and the rain moisture that got pass Sumatra will now be releasing the moisture laden atmosphere onto the Malaysian west coast.
And when it hits the cool mountain range like the Titiwangsa range it will precipitate. So you just might experience a cold wet weather in Cameron Highlands not just the lowlands in Malaysia!
