Dead Birds Shut Down 3 DC Metro Stations

Three Metro train stations were briefly closed Sunday while hazardous materials crews investigated dozens of dead birds and a substance believed to be a commercial pest poison. No human injuries were reported.  All signs point to a contractor making a mistake, said a spokeswoman for the Washington Metropolitan Area Transit Authority. The poison was spread outside at least six Metro stations.

The FBI's joint terrorism task force and officials from the National Institutes of Health joined the investigation as reports of the dead birds increased during the day.  "They are observing it; they are gathering information," said a District of Columbia fire and EMS spokesman. "There is no indication at this point that this is an attack that has been aimed at people."

The issue raised public safety concerns because there were no details on what may have caused the problems or the contractor's name. No problems were expected during the Monday morning rush hour she said.  (Media Sources)

Montana Fire Spreads Nearly Unchecked

Hot, dry and windy weather helped a wildfire near Glacier National Park grow to roughly 5,000 acres on Sunday and continue to threaten an evacuated lodge.  The blaze had grown from 1,000 acres a day earlier and was just 2 percent contained, a fire information officer said. The fire was running into heavy timber.

Authorities reopened a highway near the park in northwestern Montana, but they warned that U.S. 2 could be closed again if the blaze flared up.

Guests and 18 workers at the Summit Station Lodge along the highway remained evacuated as flames burned within a mile. Fire crews were protecting the lodge and tearing down some trees that were close to cabins.  No other structures were threatened, but officials in Pondera County asked residents of Heart Butte to be prepared to evacuate if needed. The community of about 700 people is 18 miles southeast of the blaze.

Near-record heat and low humidity also fueled blazes elsewhere in Montana, with similar conditions forecast for Monday.  A fire north of Helena was keeping people away from recreation areas and homes. The blaze, which had charred nearly 10 square miles, was 10 percent contained on Sunday, July 29, 2007 fire managers said.

Elsewhere, a dozen homes were ordered evacuated Sunday in California's Santa Barbara County as a wildfire spread across 1,000 acres, continuing a new growth spurt for the nearly month-old blaze that had appeared to be standing still.  The blaze had charred about 32,000 acres, or 50 square miles, since it started July 4 and was 70 percent contained Sunday, July 29, 2007.

An evacuation order was issued for the Peachtree Community, about 12 homes spread over a wide area of the forest. Smoke drifted over Santa Barbara more than 40 miles away and was reported in Bakersfield some 80 miles away.   (Media Sources)

Researchers: Atlantic Tropical Storms Have Doubled

The number of tropical storms developing annually in the Atlantic Ocean more than doubled over the past century, with the increase taking place in two jumps, researchers say.  The increases coincided with rising sea surface temperature, largely the by-product of human-induced climate warming, according to the researchers. 

However, an official at the U.S. National Hurricane Center called the research "sloppy science" and said technological improvements in observing storms accounted for the increase.

The annual average jumped to 10 tropical storms and five hurricanes from 1931 to 1994. From 1995 to 2005, the average was 15 tropical storms and eight hurricanes annually.  Even in 2006, widely reported as a mild year, there were 10 tropical storms.  (Media Sources)

Tropical Weather Outlook

Atlantic/Caribbean/Gulf of Mexico:
A broad area of low pressure is centered about 200 miles west of Bermuda.  Upper-level conditions could become more favorable for tropical or subtropical development over the next day or so as the system moves north-northeastward at 10 to 15 mph.  Locally heavy rain and gusty winds associated with this disturbance will move across Bermuda today, July 30, 2007. 

Elsewhere, tropical cyclone formation is not expected during the next 48 hours.

Eastern Pacific:
Shower activity continues to be poorly organized in association with a low pressure area centered about 900 miles south-southwest of the southern tip of Baja California.  As the system moves west- northwestward at about 10 to 15 mph any further development is expected to be slow to occur due to strong upper-level winds.

Elsewhere tropical cyclone formation is not expected during the next 48 hours.

Western Pacific:
Typhoon (TY) 05w (Usagi) located approximately 334 miles south of Iwo To has tracked west-northwestward at 10 mph over the past six hours.  Maximum sustained winds - 86 mph, gusts 104 mph.  Maximum significant wave height is 22 feet.  (NOAA, National Hurricane Center, Central Pacific Hurricane Center and the Joint Typhoon Warning Center)
