PROJECT ALERT NOTICE (HI) Hurricane Lane Post-event Activities

Date: Sun, 26 Aug 2018 14:13:36 EDT

Summary: USGS crews making preparations to to collect post-event data as Tropical Storm Lane leaves Hawaii

There were no new significant streamflow peaks at gaged streams in Hawaii during the last 24 hours as Tropical Storm Lane continued to weaken and move west. The heaviest rainfall from this storm fell on the northeast sides of Hawaii and Maui islands, with the other islands in the state receiving heavy rains only at the highest elevations. Wind damage was not a significant impact of this storm for Hawaii.

Record and near record (2nd or 3rd highest) streamflow peaks occurred at streams in northwest Maui and Hawaii islands, as noted in Project Alert reports in previous days.

No gages appear to have been damaged or destroyed during this event, and all real-time gages are currently transmitting.

Pacific Island Water Science Center (PIWSC) crews are preparing to go to Maui and Hawaii Island tomorrow morning to visit crest stage gages and make indirect measurements where needed. At this time, it is planned for 2 crews of 2 hydrographers to work on each of those islands. Additionally, the PIWSC is working with Water Mission Area staff and other USGS Centers to propose high water mark data collection at ungaged sites for FEMA in the area around Hilo.
