Special Weather Statement issued December 6 at 7:11PM HST by NWS Honolulu HI
Additional Details Here.
Latest radar data indicate that the volcanic ash from Kilauea's Halemaumau Crater during episode 38 has decreased this evening. Radar observations show that the volcanic plume rises to 13,000 feet above mean sea level. Light ashfall is drifting southwestward within 5 miles away from the volcano. Continue to avoid excessive exposure to ash which is an eye and respiratory irritant. Those with respiratory sensitivities should take extra precaution to minimize exposure. This will be the last update for light ashfall from episode 38 unless significant changes in volcanic activity occur.

Web cams, satellite, and radar data indicate that volcanic ash is emanating from Kilauea's Halemaumau Crater following the beginning of Kilauea's eruption episode 38 earlier this morning. Latest satellite and radar imagery shows that the ash cloud is moving due east early this afternoon, and web cams suggest that light ashfall will be possible downwind of this plume, primarily in the Puna District. Avoid excessive exposure to ash which is an eye and respiratory irritant. Those with respiratory sensitivities should take extra precaution to minimize exposure.
