Typhoon Mawar Update #10

Typhoon Mawar continues to weaken and suffer from increasing wind shear and continuous entrainment of dry air. It was last located approximately 230km southeast of Okinawa or about 140km southwest of the Daito Islands. Maximum sustained winds are down to 160kph with gusts of up to 195kph. Mawar is currently moving northeastward at 20kph.

Latest radar image from JMA shows the steady rain with bands of heavy rain from the eyewall approaching Daito Islands. Surprisingly, Okinawa has remained relatively dry--which is due to the western periphery taking a blow from the worsening atmospheric conditions in the region. Nearly 100mm of rain has already fallen in Minami-Daito while around 10 to 30mm has fallen in Okinawa. We no longer expect continuous rains in Okinawa although heavy rains should continue for Daito Islands. For more radar images, click HERE (JMA)

The infra-red image shows an eye appearing although the eyewall has collapsed. A good outflow continues to sustain the typhoon's strength and is keeping the eastern periphery strong and developed. Nevertheless, the strongest of winds remain near the core and is no longer expect to affect Okinawa. They will still feel tropical storm gusts from time to time though. Daito Islands, on the other hand, should keep feeling ttropical storm-force winds with the worst conditions occurring from 9am to 3pm today; there could winds of more than 120kph here (typhoon-force). In addition, rains of up to 150mm could still fall in Daito through tonight. Conditions in the region should start to improve tomorrow morning (Wednesday).

We'll have another update later this afternoon.
