高温范围在缩小、强度在减弱，但旱情仍在发展。昨日，武汉中心气象台有史以来第一次发布干旱红色预警：预计未来一周，随州、荆门、襄阳、孝感、咸宁、黄石等地32个县市综合气象干旱指数将达到特旱等级。
根据最新气象资料分析，随着副热带高压主体北抬，受其底部偏东气流影响，未来10天，我省部分地区有分散性阵雨发生，但降雨总量继续偏少，旱情仍将持续发展，鄂北岗地干旱继续加重。另外，据预测，我省秋季降水仍呈偏少趋势，可能产生夏秋连旱，气象部门提醒，要做好抗长旱、抗大旱的准备。
受台风“尤特”影响，我省高温范围进一步缩小、强度进一步减弱。由于副热带高压北抬，预计未来10天，南部气温会下降到35℃左右，而北部最高气温继续维持在37℃至39℃。
据介绍，干旱红色预警信号是最高级别的干旱预警，特旱为50年以上一遇的气象干旱、或有60%以上的农作物受旱。
