Unstable conditions produced a short spell of light to moderate showers across the interior of mainland St. Vincent earlier today, resulting in a dense mixture of ash within some rivers (mudflows - lahars). The extremely fast and dangerous currents were observed in red and orange zones. A few isolated showers are likely within the next 24 hours, however more significantly, late Wednesday could see an injection of additional atmospheric moisture as a trough inches closer to the islands. A favourable upper level environment could produce some moderate showers on Thursday with occasional activity on Friday as instability lingers. Residents and motorists should remain alert due to rain-soaked ash and poor visibility in volcanic ash.
