UPDATE: 4:03 p.m.
The National Weather Service in Honolulu has issued a flood watch for all major islands until 6 p.m. Monday.
A flood watch means that conditions are favorable for flash flooding," according to forecasters.
Flash flooding caused by excessive rainfall is possible due to showers moving over the islands from the south, causing leeward and urban areas to potentially receive significant flood and property damage due to rapid runoff.
"A surface trough will develop west of the islands, allowing deep moisture to move over the islands from the south. While rainfall may be light at first, heavier slow-moving showers are expected to develop, bringing the potential for flash flooding," according to a statement.
