• A Slight Risk (level 2 of 4) of excessive rainfall has been identified for Thursday, with localised heavy downpours capable of producing high rain rates over short periods.

Impact & Risks

Localised heavy rainfall could lead to flash flooding in vulnerable areas, particularly in low-lying regions with poor drainage. Mariners may face hazardous conditions due to strong southeast winds and building seas, potentially requiring Small Craft Advisories. While most of the rain is expected to be beneficial, isolated areas may experience significant impacts from high rain rates.
