Isn't it odd that a Blocking High should be such damp weather?
Look up news: "flood" on the net though and you can guess what might be about to occur.
And so:
Etna (Sicily, Italy): Lava effusion and pulsating low lava fountains continued from the New SE crater throughout the night and today. Tremor remains at fluctuating elevated levels but with a now slightly decreasing trend. The lava flows have descended the western slope into the Valle del Bove where they spread into several broad fronts.
Shiveluch (Kamchatka): Explosive activity of the volcano continues. Since the larger explosion on 11 June, the volcano has only produced a few smaller explosions and ash emissions.
Not much glow is currently visible on clear night-time images, suggesting that extrusive activity of the lava dome is reduced at the moment.
Batu Tara (Sunda Islands, Indonesia): Activity at the volcano is relatively intense at the moment. Several ash plumes rising to 5-7,000 ft (1.5-2.1 km) altitude, originating from stronger-than-normal strombolian explosions, were seen on satellite imagery during the past days.
Sangeang Api (Indonesia): Small ash emissions continue at the volcano. VAAC Darwin last reported a volcanic ash plume rising to approx. 7,000 ft (2.1 km) and extending 30 nautical miles to the NW on Saturday.
Kavachi (Solomon Islands): Some intermittent eruptive activity seems to be occurring at the volcano. On 10 June, another spot of discolored water had been visible above the shallow submarine volcano.
Pavlof (Alaska Peninsula, USA): Based on seismic data, eruptive activity continues at the volcano according to the Alaska Volcano Observatory. However, it has significantly dropped (if not stopped) over the past week. No hot spot is currently visible on satellite imagery.
No ash emissions or lava fountains could be detected recently. A weekly alimented lava flow could still be seen on satellite data from 9 June.
Shishaldin (United States, Aleutian Islands): Low-level eruptive activity continues at Shishaldin, although nothing was observed in cloudy satellite images over the past 24 hours. Web camera views of the volcano were obscured by clouds. (AVO)
Semisopochnoi (United States, Aleutian Islands): The earthquake swarm at the volcano that started on June 9 and escalated on June 12 continues. No eruptive activity is currently indicated and nothing was observed in cloudy satellite images over the past day. (AVO)
Ubinas (Peru): Near-continuous, but light ash emissions interrupted by sporadic explosions continue at the volcano. Two stronger explosions on 12 and 13 June produced ash plumes that rose 2.5-3.5 km above the summit.
Piton de la Fournaise (La Réunion): Seismic activity above normal background levels have been detected under the volcano past week. The prefecture decided to raise the alert level and advises climbers and hikers to avoid the rims and crater walls of Dolomieu crater due to an increased risk of rockfalls and collapses."

According to yesterday's BoM there is a lot more of this on the way. Saturday most likely, although I am still uncertain about the alternative of the vorticity being tornadic.
For example the lack of tornadoes he
http://www.spc.noaa.gov/climo/reports/140615_rpts.html with the list above followed by reports of: "Recent flooding" of course when I say that flooding follows volcanic eruptions it can only do so in the newspapers and etcetera.
Floods have to reach a certain criticality to make news and all the rest of it but... "in Cape Town has affected more than 8,000 people, News24 reported quoting the Disaster Risk Management Centre.
People of Khayelitsha, Strand, Vrygrond, Lotus River, Gugulethu, Delft and Philippi area of South Africa are more affected by the floods.
Khayelitsha area is reported to be the worst affected area, with around 7 000 people affected by the flooding."
