Tropical Storms – Roundup of Tropical Storms:
Typhoon Champi is located approximately 619 nm north of Saipan, and is tracking east-northeastward at 14 knots.
Hurricane Olaf is located about 660 mi…1065 km ESE of Hilo Hawaii and about 870 mi…1405 km ESE of Honolulu Hawaii with maximum sustained winds…115 mph…185 km/h. Present movement…N or 360 degrees at 9 mph…15 km/h.
Hurricane Patricia is located about 145 mi…235 km SW of Manzanillo Mexico and about 215 mi…345 km S of Cabo Corrientes Mexico with maximum sustained winds…200 mph…325 km/h. Present movement…NNW or 345 degrees at 12 mph…19 km/h.
Hazards affecting land: Rainfall: Patricia is expected to produce total rainfall accumulations of 8 to 12 inches, with isolated maximum amounts of 20 inches, over the Mexican states of Nayarit, Jalisco, Colima, Michoacan and Guerrero through Saturday. These rains could produce life-threatening flash floods and mud slides.
Tropical depression 26w (twenty-six), located approximately 759 nm northwest of Wake Island, and is tracking northeastward at 19 knots.
Greece – Emergency rescue workers and firefighters were searching parts of northern and western Athens on Thursday night after flash floods in the capital left at least one person dead. The weather, which included gale-force winds, caused difficulties in other parts of Greece as well.
Philippines – After bearing the brunt of Typhoon Koppu, the Philippines is now suffering floods in the northern islands.
Sea Ice Around Antarctica Declines in 2015 Peak
The sea ice around Antarctica grew to its annual peak on Oct. 6 but showed a sharp decline from the record coverage of recent years.
NASA says this year’s maximum fell roughly in the middle of what has been measured during the past 37 years of satellite observations.
Scientists said the developing El Niño probably had a strong influence on this year’s sea ice.
Rather than being in sharp contradiction to a warming climate, a greater amount of ice ringing Antarctica in the recent past has been linked to climate change.
Stronger southern hemisphere winds due to a warmer climate appear to have caused the floating ice to bunch up around Antarctica rather than drifting northward and melting.
“After three record high extent years, this year marks a return toward normalcy for Antarctic sea ice,” said Walt Meier, a sea ice scientist at Goddard.
“There may be more high years in the future because of the large year-to-year variation in Antarctic extent, but such extremes are not near as substantial as in the Arctic, where the declining trend towards a new normal is continuing,” Meier added.

Global Temperature Extremes
The week’s hottest temperature was 109.4 degrees Fahrenheit (51.6 degrees Celsius) at Matam, Senegal.
The week’s coldest temperature was minus 92.0 degrees Fahrenheit (minus 68.9 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
Shiveluch (Kamchatka): A moderately sized pyroclastic flow as result of small collapse of part of the active lava dome occurred this afternoon (Kamchatka time), sending an ash plume to approx. 15,000 ft (4.5 km) altitude.
Sakurajima (Kyushu, Japan): The volcano has been relatively calm during the past weeks. JMA reported small explosions at the Showa crater during 13-16 October. The Alert Level remained at 3 (on a 5-level scale).
Batu Tara (Sunda Islands, Indonesia): Ash plumes from the volcano have become an almost daily observation on satellite data monitored by VAAC Darwin. This suggests that activity has picked up at the volcano (we will find out more when we are going there in November). This morning, a plume at 5,000 ft (1.5 km) altitude drifted 35 km W from the volcano.
Dukono (Halmahera): Ash emissions continue to be intense and near continuous. VAAC Darwin reported again an ash plume extending 50 km NW from the volcano this morning.
Piton de la Fournaise (La Réunion): According to local news, the eruption restarted today after 4 days of quiet. Observers detected minor strombolian activity from a small, 1 m diameter vent at the bottom of the large new cone. Small explosions every few seconds were seen sending lava bombs to a few tens of meters height, not surpassing the outer crater rim. According to volcano observatory, sporadic pulses of tremor have reappeared this morning since 7am local time. Whether this is just a weak after-play or the onset of a more significant eruptive phase of the latest eruption remains to be seen.
