Western USA – Rain, snow and wind hit the U.S. West on Wednesday, flooding roads, toppling trees and cutting power while raising threats of debris flows from wildfire scars. The tempest, aimed at California and southern Oregon and barreling toward Nevada, was feeding on a deep plume of moisture stretching across the Pacific Ocean to near Hawaii. The storm followed more than a week of severe weather in the Pacific Northwest and was the latest in a series that has all but eliminated drought-level dryness in California this winter. Winter storm warnings were posted in the snow-laden Sierra Nevada, where the forecast says up to 7 feet (2.1 meters) of new snow could be dumped at elevations above 9,000 feet (2,743 meters). A backcountry avalanche warning was issued throughout the Sierra.

Volcanos

Global Volcanic Activity – New Activity for the week of 6 February – 12 February 2019

Karangetang | Siau Island (Indonesia) : On 8 February PVMBG reported that lava from Karangetang’s Kawah Dua (North Crater) continued to advance over 3.5 km down the Malebuhe River drainage on the NW flank into the ocean. Levees had formed at the margins channeling the lava down the middle of the flow. Avalanches from the edges of the flow generated brown and gray plumes. A lava delta was building out into the ocean and generating a dense steam plume. Drone footage acquired on 9 February showed that the flow was about 160 m wide where it crossed a road (about 210 m from the coast) and about 140 m wide at the coast. Seismicity remained high. The Alert Level remained at 3 (on a scale of 1-4), and residents were warned to remain outside of the 2.5-km exclusion zone around the N and S craters, and not enter within 3 km WNW and 4 km NW.

Poas | Costa Rica : OVSICORI-UNA reported that seismic and infrasound data indicated multiple events at Poás during 7-8 February. On 8 February events were centered at vent A (Boca Roja) and produced plumes that rose no higher than 200 m and drifted SW. A sulfur dioxide odor was reported in areas downwind including San Jose de Naranjo, Grecia (16 km SW), Poás, Sarchá, Naranjo, and Atenas (32 km SW). Incandescence in the crater began to be visible at 0151 on 11 February. Passive ash emissions rose 200 m and drifted SW.
