Latest numerical weather guidance continues to point to the development of another tropical disturbance in the Wednesday to Saturday time frame. However, there are significant differences in the various models. This could pose a threat of higher winds and waves affecting Guam and the CNMI. However, it's far too early to determine if one or two systems form, or if two system do form, do they merge and where. Additional uncertainties remains in the potential strength and track. In the meantime, a persistent southwesterly monsoon will periodically bring heavy showers to the Marianas with additional rainfall totals of 4 to 8 inches, locally higher, through Thursday morning. For that reason, a flood watch remains in effect. For the latest forecasts and information please visit: - http://www.weather.gov/gum - http://www.weather.gov/safety/flood
