Tropical Storms – Roundup of Tropical Storms:

Gl sst mm

Hurricane Hilda is located about 720 mi…1160 km ESE of Hilo Hawaii and about 935 mi…1505 km ESE of Honolulu Hawaii with maximum sustained winds…125 mph…205 km/h. Present movement…WNW or 295 degrees at 12 mph…19 km/h.

Tropical Storm 13w (Soudelor), located approximately 148 nm west of Taipei, Taiwan, is tracking north-northwestward at 10 knots.

Nine persons were killed and three others missing as Super Typhoon Soudelor left behind a trail of destruction in eastern China, uprooting trees, hitting power supply and causing the heaviest rains in a century, state media reported today. Heavy downpours have caused mudslides and cave-ins led to several house collapses, affecting over 2 lakh people after Soudelor, called the biggest typhoon of the year earlier in the week with winds of up to 230 kilometres an hour, made a landfall in the Chinese coast last night.

Tropical Storm 15w (Molave), located approximately 453 nm south of Yokosuka, Japan, is tracking northward at 06 knots.

Invest 93E is an area of disturbed weather in the East Pacific that has the potential for tropical development.

India – Four persons including three members of a family were feared dead as flash floods triggered by a cloudburst wrecked havoc in Dharampur area of Mandi district, 250 km from Shimla, this morning, inundating vast areas, washing away vehicles and drowning several head of cattle.

Environment

Hong Kong Swelters

Hong Kong on Saturday recorded its hottest day since authorities began taking temperature readings 130 years ago, due to the influence of a nearby typhoon.

The daily maximum temperature hit 36.3 degrees Celsius, the Hong Kong Observatory said, with higher temperatures recorded in some parts of the city earlier in the day.

A layer of haze hung over the metropolis of seven million, as people wielding electric fans and umbrellas tried in vain to beat the boiling heat.

Europe in Heat Wave

Just one month after setting its all-time national heat record, Germany tied that mark on Friday at the same location, as yet another multiway heat wave swept across much of Europe. The German meteorological agency (Deutscher Wetterdienst) confirms that the town of Kitzingen reached 40.3°C (104.5°F) on Friday, the same national record it reached on July 5. More than 100 towns and cities in Germany either tied or broke their all-time record highs on Friday. Berlin’s Kaniswall station hit 38.9°C (102.0°F)–the hottest temperature ever observed in the Berlin area, beating the old record of 38.6°C (101.5°F).

Record heat extended far across other parts of Europe on Friday. Friday’s high of 38.3C (100.9°F] at Genoa, Italy, topped the all-time airport record by a full 4°F. Records at the airport extend back to 1962; the previous reporting site for Genoa was located further inland, with a warmer microclimate. Even at that location, the previous Genoa record was 37.8°C (100.0°F) in July 1952.

Space Events

Perseid Meteor Shower

The Perseid meteor shower — an annual display of natural fireworks — should be particularly spectacular this year, with extra-dark skies expected to create optimal stargazing conditions, astronomers said Friday.

When the celestial show hits its peak overnight Wednesday next week, up to 100 shooting stars per hour will streak across the sky for a spectacle visible around the globe.

Volcanos

Roundup of Global Volcanic Activity

Cleveland (Aleutian Islands, Alaska): AVO reported that during 29 July-4 August satellite images detected strongly elevated surface temperatures at the volcano’s summit consistent with growth of a new lava dome. A field crew working in the area on 1 August reported frequent rockfalls on the volcano. A weak infrasound signal was much smaller than the explosion detected on 21 July; the signal may have been related to gas emissions, also consistent with lava-dome effusion. A very small gas plume was visible in webcam images during 2-3 August, and steam emissions were observed on 4 August.

Nevado del Ruiz (Colombia): Sporadic ash emissions continue to occur from time to time at the volcano. A tremor episode on 6 August that started at 08:39 local time and lasted a few minutes was accompanied by the expulsion of ash that rose approx. 700 m. Light ash fall occurred in Manizales, Villamaria, Cinchina, Santa Rosa and Pereira.

Sabancaya (Peru): The volcano remains restless. A diffuse plume with light ash content is rising most of the time from the summit crater.

Shiveluch (Kamchatka): A moderately sized eruption occurred Thursday evening and produced an ash plume that rose to approx. 18,000 ft (5.4 km) altitude. Minor, near continuous ash venting has been intermittently visible on webcam imagery since.

Aso (Kyushu): The eruption from Aso volcano’s Nakadake crater continues. During the past day, several phases of ash emissions occurred. At night, incandescence can be seen at the vent. The activity is not typical strombolian with discrete explosions, but rather continuous phases of jet-like venting of ash. Its cause is probably phreatomagmatic – the release of hot ash and gas as water and magma interact at depth.

Nishino-shima (Volcano Islands, Japan): The volcano on the island continues to erupt lava flows that continue to gradually enlarge the island. The latest survey by the Japanese coast guard shows that lava flows have been traveling mostly through a tube system towards the east, where active flows continue to add land to the coast.

Manam (Papua New Guinea): Ash emissions yesterday and today produced a plume that rose to estimated 21,000 t (6.5 km) and drifted SSW. (VAAC Darwin)

Raung (East Java): Intense ash emissions continue to produce a plume that stretches hundreds of kilometers to the SW. Many flights to and from Bali were canceled or delayed today again. The detected heat emission, based on satellite data from NASA’s MODIS sensor, remains elevated, although it has decreased significantly during the past days.
