Tropical Storm 27W remains active, moving by not far southwest of Guam… generally towards Japan

Here’s a satellite image of this system, along with a looping satellite image, larger looping view…and what the computer models are showing

The Joint Typhoon Warning Center reports that satellite images show a broad area of deep disorganized convection struggling to wrap into the low level circulation center.

Upper level analysis shows improvement over the past 6-hours, due to a decrease in easterly flow. Meanwhile, wind shear is diminishing into the marginal to favorable category. Sea surface temperatures in the region are also very warm.

This storm will continue to strengthen over the next 24-36 hours, which will accelerate 27W towards the northwest…reaching a peak intensity of 90 knots by 72 hours. Beyond 72 hours wind shear will increase, leading to a weakening trend…with the (then typhoon) staying south of Japan.

Maximum sustained winds as of JTWC Warning #18 sustained winds were 40 knots with gusts of 50 knots.
