Global Hazards and Significant Events
for July 2002
Violent thunderstorms which developed in the Henan province of central China on the 19th produced egg-sized hail in the city of Zhengzhou. The storms killed at least 25 people and injured 200 (CIP report).
While heavy rains affected parts of northeastern India and neighboring Bangladesh, the remainder of the India had notably drier weather during July. The northwest agricultural states of Haryana, Punjab and Rasthan missed the early season rainfall during June and early July and have experienced drought conditions. On the 24th, the Indian Agricultural Minister characterized drought in the country's breadbasket as the worst in a decade (Associated Press). a time series depicting precipitation anomalies across India since 1900

Drought conditions continued across southeast Australia, with around two-thirds of New South Wales experiencing an extended period of dry weather. On July 18th, the Australian government announced a drought aid package for farmers designed to curtail individual agricultural losses (Associated Press).

Rainfall in Sydney was one-half the normal (48.8 mm or 1.92 inches) July amount. Nationally, it was the fifth driest July since 1890 and the driest since the severe drought of 1982, according to the Australian Bureau of Meteorology.

Numerous wildfires, sparked by lightning and aided by very dry conditions, burned out of control in parts of northern and central Quebec. Nearly 85 fires were reported, with the largest fire charring more than 400 square miles (100,000 hectares) of forest (AP). The smoke plumes created by the fires were transported into the northeastern United States by the 7th-8th, drastically reducing visibility (see image to the right). a satellite image depicting Canadian fires and smoke over the Northeast US

Hot weather covered much of the United States, including the southern Rockies, the Great Lakes and into the Northeast where daily temperatures were 3 to 7°C (5.4-12.6°F) above normal across much of the region during July 1-5. Daily maximum temperatures exceeded 32°C (90°F) in many areas.

During July 6-14, the hottest temperatures were concentrated across the western United States, where numerous all-time high temperature records were broken. On July 13, Death Valley, CA recorded a high temperature of 127°F (52.8°C) with a low of 100°F (37.8°C), or a mean temperature of 113.5°F (45.3°C). This is the second warmest mean temperature at Death Valley since records began at the current station in 1961.

Under conditions of severe drought, intense heat and low humidity, numerous large wildfires continued to burn across parts of the western United States. An increase in the coverage of showers and thunderstorms across the region during the 10th-16th brought temporary relief to firefighting efforts. a depiction of wildfire locations in the southwestern US on July 5, 2002

rainfall estimates in Texas during June 30-July 7, 2002 (inches)
Texas Daily Rainfall Estimates
A slow moving storm system brought very heavy rains to parts of central and southern Texas during June 30-July 6, where locally more than 102 cm (40 inches) fell in some parts of the greater San Antonio area. The Texas Division of Emergency Management estimated that heavy rain and flooding affected 29 counties surrounding San Antonio, resulting in at least 9 deaths (AP). Texas Governor Rick Perry estimated that property damage would be in the hundreds of millions of dollars and President Bush declared 24 counties disaster areas (New York Times).

In the interior Xinjiang province of China, 11 people were killed by floods which occurred during the 21st-28th. Flooding rains across southeast China's Guangdong province affected around 31,000 people and were responsible for at least 9 deaths during the week of the 15th-21st. Farther east in the Philippines, flooding during the same period resulted in 65 deaths and the destruction of nearly 2,000 houses (CIP report).

Dongting Lake, one of China's largest freshwater lakes located in the central province of Hunan, threatened the homes of more than 1 million people (AP). Heavy rainfall in June brought the lake level to 32 meters (105 feet) in early July which is considered the warning level for the introduction of flood prevention measures. The lake, which covers 2,700 square kilometers (1,080 square miles), empties into the Yangtze River and flows past some of China's biggest cities and most heavily populated agricultural areas. Floods in June killed 53 people in Hunan province (Xinhua).

Heavy monsoon rains brought flooding to parts of northeast India, where nearly 300 people have died since the rains began in late June. In neighboring Bangladesh, 123 people died and up to 5 million people were affected as nearly 20 percent of country was inundated by flooding during July (Associated Press/OCHA).

Fengshen developed on the 14th and rapidly strengthened into a typhoon on the 15th while tracking over open Pacific waters. The storm reached maximum intensity on the 21st at sea when maximum sustained winds were near 270 km/hr (~145 knots or 165 mph). The typhoon weakened into a tropical storm and affected the Japanese islands of Tanegashima and Yaku Jima on the 25th with heavy rain and winds gusting over 90 km/hr (50 knots or 55 mph). Fengshen dissipated as it crossed into northeastern China on the 27th.

Fung-Wong developed on the 21st and remained over open Pacific waters, becoming a minimal typhoon on the 23rd. Fung-Wong weakened below typhoon strength by the 25th, with maximum sustained winds near 90 km/hr (~50 knots or 55 mph). The storm weakened into a depression and dissipated across southern Kyushu in Japan on the 27th. Farther west, tropical depression 13W crossed over the Philippines bringing heavy rainfall during July 18-22.

Halong originated across Micronesia on July 7th, became a typhoon on the 9th and passed just south of Guam on the 10th, producing heavy rains and winds gusting to 70 km/hr (~40 knots or 45 mph) on the island. Halong weakened into a tropical storm before crossing the island of Honshu on Japan on the 16th with maximum sustained winds near 75 km/hr (40 knots or 45 mph). The storm forced hundreds of schools to close in Tokyo, seriously disrupted transportation and caused power outages to over 23,000 households (Associated Press). a satellite image of typhoon Halong passing just south of Guam
