Weather Situation

The monsoon trough lies across the northern Coral Sea. Tropical Low 12U [1000 hPa] is developing along the trough east of Cooktown, and is forecast to move southwest and cross the North or Far North Queensland coast on Saturday. A squeeze between 12U and a ridge of high pressure from a high [1022 hPa] over the Tasman Sea will lead to vigorous southeasterly winds south of the trough over the next several days. Meanwhile, a vigorous northwesterly monsoon flow will develop across Torres Strait during today.
