Tropical Storms – Roundup of Tropical Storms:

Gl sst mm

Hurricane Gonzalo is located about 240 mi…385 km SSW of Bermuda with maximum sustained winds…130 mph…215 km/h. Present movement…NNE or 25 degrees at 15 mph…24 km/h.

Hurricane Gonzalo roared toward Bermuda as a powerful Category 4 storm early Friday amid warnings by forecasters that the British island territory would likely be hit with damaging winds and life-threatening storm surge in coming hours.

Hazards affecting land – wind…hurricane conditions are expected to reach Bermuda on Friday. It should be noted that wind speeds atop and on the windward sides of hilly terrain are often up to 30 percent stronger than at the surface…and in some elevated locations can be even greater. Storm surge…a dangerous storm surge is expected to produce significant coastal flooding in Bermuda. Near the coast…the surge will be accompanied by large and destructive waves. Rainfall…Gonzalo is expected to produce total rain accumulations of 3 to 6 inches over Bermuda. Surf…large swells generated by Gonzalo are affecting portions of tVirgin Islands…the northern coasts of Puerto Rico and the Dominican Republic…portions of the Bahamas…portions of the southeast coast of the United States…and Bermuda.

Tropical storm Ana is located about 340 mi…545 km SSE of Hilo Hawaii and about 530 mi…850 km se of Honolulu Hawaii with maximum sustained winds…65 mph…100 km/h. Present movement…WNW or 295 degrees at 14 mph…22 km/h.

Hazards affecting land – wind…tropical storm conditions are possible on The Big Island of Hawaii starting Friday night. Surf…large swells produced by Ana are expected to build over the eastern end of the main Hawaiian Island chain through Friday morning. Rainfall…heavy rainfall associated with Ana may reach The Big Island of Hawaii Friday afternoon…with total rain accumulations between 6 and 12 inches expected.

Canada – Heavy rain and thunderstorms wreaked havoc on Toronto streets Thursday night, leaving cars stuck in water at several flooded intersections and lengthening the commute for many TTC riders trying to get home. Subway service was suspended both ways between York Mills and Eglinton stations due to flooding at Lawrence Station, which was to remain closed until the morning.

Global Temperature Extremes

The week’s hottest temperature was 111.6 degrees Fahrenheit (44.2 degrees Celsius) at Chhor, Pakistan.

The week’s coldest temperature was minus 92.9 degrees Fahrenheit (minus 69.4 degrees Celsius) at Russia’s Vostok Antarctic research station.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Roundup of Global Volcanic Activity

Popocatépetl volcano (Mexico): Activity at the volcano has remained low, with small occasional steam, gas and sometimes ash emissions. Incandescence was observed over the crater during the night. During an overflight on 14 Oct “it was observed that the inner crater, formed in July 2013, has increased its diameter, probably due to the destruction of the dome and walls collapsing, reaching an estimated 350 m diameter. The bottom of the inner crater is about 100 m below the floor of the main crater. No residues were observed of the 52nd dome, which was emplaced in the bottom of the inner crater early last August. Instead, the bottom of the inner crater is cup-shaped and is covered with tephra (fragmented material) Most emissions of steam are coming from a crack in the north wall of the inner crater, while ash emissions, originate in the bottom of the crater, in the area covered by tephra.

Bardarbunga volcano update: The eruption continues from the Holuhraun fissure with an amazing lava output at approx. 350 cubic meters per second. A large lava pond has formed over the merged main craters on the central part of the fissure, from where a river of lava flows into the plain. Earthquakes have increased under the Bardarbunga caldera, which could be a sign that something is about to change.

Stromboli (Eolian Islands, Italy): There are signs that the lava flow eruption could be approaching an end soon. Lava effusion rate has dropped although a weak lava flow continues to be active on the upper part of the Sciara del Fuoco. INGV Catania reports strong degassing and that ash emissions from the summit vents have decreased.
