Wider weather episode

A weak trough near the Leeward islands was maintaining a weak steering flow over the local islands. Instability aloft was increasing as mid level temperatures cool down. The combination of these factors, along with strong diurnal heating and enough moisture in the lower levels resulted in very strong showers and isolated thunderstorms over the area. Several reports of mudslides and flooding were received.
