This graphic is from Hurricane Lane. It only covers the 72 hours leading up to 8/25/18. In some areas total accumulation attributed to the storm topped 4 feet. We had about 3 in Hamakua. Historically, the hurricane season coincides with the driest months of the year. The ground moisture is at its lowest and growth rates tend to be reduced. Water preservation strategies used by the trees results in lower uptake of nutrients and lower uptake of Carbon Dioxide. In essence the trees are just waiting for rain. Hurricanes passing through the area are often just what the doctor ordered. The soil is dry and has tremendous capacity to take up and hold this water. A fully saturated soil profile can provide months of water to the trees it supports. Additionally, this water allows the trees to take advantage of the longer days and stronger sun of summer. Transpiration is re-invigorated, Carbon Dioxide uptake is maximal, nutrient uptake increases and growth can be remarkable. As a result, the summer hurricane season is not bad news for trees on the Hamakua coast.

Hurricane Lane brought record rainfall to Hawaii. Some low lying areas prone to flooding suffered damage. On the slopes of Mauna Kea the terrain limits ponding and abundant gulches channel the excess to the sea. It is truly a magical place to be.
