The Guizhou Provincial Meteorological Observatory issued a forecast on the 9th, saying that there will be no large-scale heavy precipitation in Guizhou in the coming week, and the drought in the province will continue to be maintained or even developed.

Based on the comprehensive analysis of the latest meteorological data, Guizhou Meteorological Observatory has no extensive precipitation process in Guizhou in the coming week.

The area is cloudy to sunny, and the eastern part has high temperature above 35 °C. Due to the high temperature and high evaporation, the drought conditions in various places will be re-developed on the original basis. It is recommended that all localities continue to do a good job in resisting major disasters, resisting drought and resisting drought.

From January to July this year, the total precipitation in Guizhou was 4 to 50% less than that in normal years, and in most of the regions in July, it was 5 to 10% less.
