Tropical Storm Higos Update #1

Issued (2230 UTC) 630am PhT

Tropical Storm Higos is the second name cyclone to form this 2015 season. The system is currently in the middle of the Pacific and is not an immediate threat to land. TS Higos was last located approximately 1,300km east of Guam. Maximum sustained winds are at 110kph with gusts of up to 140kph. TS Higos is moving west northwestward at 10kph.

Latest satellite image shows Higos with good symmetrical appearance with excellent poleward outflow. Convective activity also continues to improve and further analysis reveals an eyewall that is near completion. Higos is moving across a relatively favorable region with moderate wind shear and warm sea surface temperatures.

We expect the Japan Meteorological Agency to upgrade Higos into a Typhoon later today (JTWC has already upgraded the system). Higos is forecast to continue moving generally northwestward but should eventually turn more to the north in response to a mid-latitude trough moving across the North Pacific.

This trough should steer Higos away from the Mariana Islands. We don't expect any significant impacts from this system aside from high waves across the Mariana Islands in the coming days.

We'll have another update later today.
