Widespread heavy showers and thunderstorms are occurring over the East Pacific, supported by convergence along the monsoon trough and enhanced by tropical waves moving through the region. A tropical wave in the western Caribbean will move into the EPac in the coming days.

A strong pressure gradient between high pressure over the central Atlantic and lower pressure over South America will support pulsing strong winds and locally rough seas in the south-central Caribbean this week. Locally strong winds will also be possible in the Gulf of Honduras.

Scattered showers and thunderstorms are occurring near a pair of surface troughs in the western Atlantic, east of the Bahamas and north of Greater Antilles. Gusty and erratic winds and rapidly building seas are possible near thunderstorms.
