Post Tropical Storm Simon is located about 45 mi…75 km WSW of Punta Eugenia Mexico with maximum sustained winds…35 mph…55 km/h. Present movement…NE or 40 degrees at 7 mph…11 km/h.

Hazards affecting land – rainfall…Simon is expected to produce total rainfall amounts of 1 to 3 inches across the northern parts of the Baja California Peninsula and Sonora in Mexico through Wednesday. Surf…swells generated by Simon are affecting portions of the Baja California peninsula. These swells are likely to cause life-threatening surf and rip current conditions.

Typhoon 19w (Vongfong), located approximately 510 nm south-southeast of Kadena AB, and is tracking northwestward at 07 knots.

Super Typhoon Vongfong became the strongest tropical cyclone of 2014 and fifth super typhoon (150 mph max sustained winds or higher) of the year after intensifying rapidly overnight Monday into Tuesday, U.S. time.

Tropical cyclone (tc) 03b (Hudhud), located approximately 562 nm south of chittagong, and is tracking west-northwestward at 09 knots.

France – Torrential rains Monday night left a trail of destruction in southern France. Overnight flash floods overturned cars, damaged roads and flooded homes as well as Mosson Stadium in the southern city of Montpellier. In just a matter of hours, the area just north of the city was hit with more than 10 inches of rain, more than double its monthly average.

Disease

Ebola Spread in Europe “Unavoidable”

The spread of Ebola across Europe is “quite unavoidable”, the World Health Organisation has warned as four people were in hospital after a Spanish nurse became the first person known to have contracted the virus outside Africa.

WHO European director Zsuzsanna Jakab has said while more cases will spread in Europe, the continent should be well prepared to control the disease.

Health officials in Spain today said four people – the nurse, her husband and two others – were being monitored in hospital in a bid to stem the spread of the virus. The nurse’s dog has been ordered to be put down.

Dengue Fever in China

An outbreak of dengue fever in the southern Chinese province of Guangdong has killed six people and infected thousands more, state media report.

Provincial health authorities said that as of early Tuesday, more than 23,000 had been infected.

State news agency Xinhua said the outbreak is believed to be the worst in China for 20 years.

The tropical disease, which is spread by mosquitoes, causes high fever and severe joint pain.

Chinese authorities have attributed the outbreak to high temperatures and wet weather, and increasing travel to dengue-prevalent places.

The number of mosquitoes is also said to have increased five-fold.

Wildfires

Wildfires – California

The pilot of a single-person airtanker was killed Tuesday afternoon when his plane crashed while fighting a rapidly spreading northern California wildfire, state fire officials said. Crews found the plane after it disappeared while flying over the Dog Rock Fire near the Arch Rock in Yosemite National Park.

Volcanos

Roundup of Global Volcanic Activity

Stromboli (Eolian Islands, Italy): Lava continues to flow from the effusive vent under the NE crater and forms several active branches on the upper Sciara del Fuoco. When observed last evening, the most advanced flow fronts were at 500-550 m elevation. Near-constant glowing rockfalls detach from the lava flows, sometimes reaching the lower parts of the Sciara. Occasional ash emissions, sometimes with audible detonations occurred from the western vent at the summit craters.

Bardarbunga (Iceland): The eruption and seismic activity at the Holuhraun fissure continue with little variation. The Baardarbunga caldrta continues to subside at approx. 50 cm a day, accompanied by frequent earthquakes. Two magnitude 5.0 and 5.5 events yesterday were associated with a drop of the floor by approx. 60 cm alone! IMO wrote: “Seismic activity around Bárðarbunga, and volcanic activity at the eruption site at Holuhraun, has been comparable to recent days. Seismicity is low in the dyke intrusion; since the last report at 07:00 this morning around 15 earthquakes have been detected in the northern part of the dyke (less than 20 since midnight) and the strongest one was magnitude 1.1. About 25 earthquakes have been detected around the Bárðarbunga caldera rim during the last 12 hours (40 since midnight), the strongest event there was magnitude 5.5 at 10:22 on the southeastern rim (and since midnight a 5.0 earthquake on the northwestern rim at 03:51 must be included). Additionally, eight more earthquakes exceeded magnitude 3 since 07:00 (11 since midnight).

Copahue (Chile/Argentina): A new phase of ash emissions began on the evening of 4 Oct. The volcano started to emit near continuous ash plumes, interrupted by strong degassing phases, from the active El Agrio crater. Seismic activity according to SERNAGEOMIN has been low suggesting that the origin of the new eruptions is phreatic, i.e. driven by steam explosions rather than fresh magma rising to the surface. No incandescence has been observed, a further sign that the temperature is relatively low, typical for phreatic activity, and no thermal signal is visible on satellite data. Copahue volcano started a phase of unrest in late 2012 with seismic swarms and increased degassing. Its alert level was lowered back to Green in April 2013, but activity picked up shortly again, in May, and increased to the point that a magmatic eruption was considered a possibility. Volcanic alert level was raised to red, along with evacuations as precaution.
