The 35th tropical wave of the 2019 Atlantic Hurricane Season moved west of Trinidad and Tobago. The 36th tropical wave of the 2019 Atlantic Hurricane Season is approaching Trinidad and Tobago, forecast to move across the area Saturday into Sunday.

Tropical waves typically have fair weather ahead of the wave axis, though other features in the area such as surface troughs, increased atmospheric moisture, and local climatic effects, to name a few, may trigger showers and the odd thunderstorm. Following the passage of the wave, much of the active weather typically associated with a tropical wave occurs.
