にわか雨続く 林間は泥濘に注意

Kiroro is forecast to experience rain throughout the day. Light drizzle will begin in the morning, intensifying to light showers from noon to 3 PM, with a 100% chance of precipitation. The summit (elevation 1180m) will see temperatures in the mid-15s Celsius, with about a 4-degree difference from the base. Although winds are calm, the rain will make the perceived temperature feel lower than forecast.

Ground conditions will be wet all day, with many muddy sections, especially on the gentle to moderate slopes of the Asari-dake northeast face and within the forest tree run routes. Extreme caution is advised for slippery footing. No snow is present, so crampons or microspikes are not needed, but waterproof and breathable rain gear, both jacket and pants, is essential.

Layering should consist of a wicking base layer, a light fleece or synthetic shirt as a mid-layer, and waterproof-breathable rain gear. During activity, prevent sweat chill, and quickly put on rain gear during breaks to avoid getting cold. While the risk of strong winds on the summit ridge is low, obstacles within the tree runs will be harder to spot due to rain, requiring extra vigilance.

Light drizzle will continue into the evening, with temperatures dropping to the low 12s Celsius overnight. Prolonged activity in wet conditions increases the risk of hypothermia, so an early finish to your outing is recommended.
