The Meteorological Department says Typhoon Noru, currently threatening Vietnam after pounding the Philippines, will weaken to a tropical storm before it crosses into Thailand on Thursday.
Director-general Chomparee Chompurat said on Tuesday that at 10am Typhoon Noru was about 380 kilometres southeast of Danang and would land in central Vietnam on Wednesday.
It would then weaken to a tropical storm and reach the central and lower Northeast on Thursday, before degrading into a depression.
