Hong Kong Issues Amber Rainstorm Warning as Texas Faces Flash Floods and Southwest New Mexico Sees Fire Weather Alerts
Hong Kong issued an amber rainstorm warning Tuesday as persistent heavy showers and thunderstorms from a trough of low pressure affect the region, while parts of Texas face ongoing flash flooding and the U.S. Southwest contends with critical fire weather conditions.
Hong Kong Under Amber Rainstorm Warning
The Hong Kong Observatory issued an amber rainstorm warning at 6.15pm on Tuesday. [1] This warning signals that more than 30mm of rain had fallen or was expected to fall across the city within an hour. [1] Heavy showers and squally thunderstorms associated with the southwest monsoon and a trough of low pressure are affecting the coast of Guangdong and the northern part of the South China Sea persistently. [1] The forecaster said downpours were likely to continue. [1] Unsettled weather is expected over the next few days. [1]
Forecast for Continued Heavy Showers in Southern China
The trough would continue to influence the region in the coming days. [1] This influence brings further heavy showers and thunderstorms. [1] With the subtropical ridge over the western North Pacific forecast to extend westwards later in the week, showers over Guangdong were expected to ease gradually. [1] The Hong Kong Observatory noted that the unsettled weather linked to the southwest monsoon and trough of low pressure affects the Guangdong coast and northern South China Sea. [1]
