General Situation:
The easterly airstream now affecting the coast of Guangdong
will be replaced by a southerly airstream gradually in the

the weather is expected to be unsettled over southern China
midweek this week. With an anticyclone aloft strengthening
gradually, the weather will improve and it will be
persistently hot over the coast of southern China in the
latter part of this week to early next week.
