Tropical Depression 06W has intensified rapidly overnight and has been upgraded to Tropical Storm Tapah. The storm's center was last located approximately 360km northeast of Guam. Maximum sustained winds have increased to 100kph with gusts of up to 130kph. TS Tapah is moving northward at 15kph.

As of 8am this morning, Tropical Storm Warnings are in effect for Alamagan, Pagan, Saipan, and Tinian. A Typhoon Watch is in effect for Alamagan and Pagan. Please monitor the developments of this cyclone and always follow the forecasts and warnings of your local officials.

Latest satellite image shows the central convection continuing to strengthen and expand. Tropical Storm Tapah remains in a region favorable for further development. Sea surface temperatures are warm enough and upper-level winds support excellent poleward outflow. Dry air is also kept at a minimum.

Tropical Storm Tapah will continue moving northward before turning northwestward and will pass well north of Guam and Saipan. Windy conditions and occasional rains are still possible, however. The northern portions of the Mariana Islands will experience stormy conditions over the next 24 to 48 hours.

We'll have another update later today.hg
