Hydrologic Outlook
Alert:
...HEAVY RAIN AND FLASH FLOODING POSSIBLE FROM TUESDAY INTO THE 
WEEKEND... 
 
A low pressure system will develop west of the islands early this 
coming week bringing the potential for widespread heavy rainfall. 
The duration and intensity of rainfall will bring the potential for 
flooding impacts as early as Tuesday for Kauai, and Wednesday onward 
for the remainder of the area. 
It is too soon to forecast rainfall amounts or where the heaviest 
rain may fall, but leeward areas are as likely to experience heavy 
rainfall as windward areas. 
Keep up to date with the latest forecast information through the 
Internet (weather.gov/hawaii), local media, social media, or NOAA 
Weather Radio broadcasts. 
An updated outlook will be issued by 6 AM HST Sunday or sooner if 
necessary.
