The winds in the Hachijo area are expected to weaken and shift as follows. By
0600 UTC on Saturday, WNW at 20 kt; by 1200 UTC Saturday,
WNW 25 kt; by 1800 UTC, NW at 15 kt; by 0000 UTC on Sunday, April 1, NW at 20
kt; and by 0600 UTC on Sunday, NW at 15 kt. The
clouds should decrease in the Hachijo area during this time, with the
possibility of cloud streets because of the cold air flow over relatively warm
water. A trajectory calculation for Hachijo, Image 1, indicates that at 0000 UTC
on Sunday the air flow will be from the NW, with near- surface air
having crossed over Japan 6-18 hours earlier.

The winds will also vary in the Cheju area. From now until Sunday morning the
direction will remain NW and the winds will weaken from over 25 kt
to less than 15. Later on Sunday the winds will shift to the SW, and after
Sunday night will increase again to over 15 kt.

The weather depiction for Monday, April 2, Image 2, represents the situation at
0000 UTC, 0900 JST. The anticyclone which was near 125 E on
Saturday, March 31 will have moved toward the SE, and is shown south of 30 N,
east of 145 E. However, high pressure continues to dominate west
to approximately 125 E, south of 35 N. A new low pressure center will form near
the NE coast of China late on Sunday, and will develop and move
quickly through the position shown, approximately 43 N, 137 E. The strong winds
associated with the pressure gradient generated by this and the
high pressure further south will result in strong offshore flow in the area
south of 40 N, with the possibility of uplift in the area near 38-40 N, 135 E.
