Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Strong Quake Strikes Baffin Bay

Posted by feww on July 8, 2009

Magnitude 6.1 Earthquake Occurred at Baffin Bay off the NW Coast of Greenland

FEWW Moderators believe magnitude of the seismicity most likely intensified as a result of icemelt in the region.

Other examples of climate-intensified natural events would be posted on this blog when they occur.

Hurricane Ike: Who Rubbed the Oil Lamp? [Update 9/12]

Posted by feww on September 12, 2008

Ike has a 78 percent chance of strengthening to a major hurricane before landfall with sustained winds of at least 178km/hr (111mph). ~ FEWW Forecast.

Ike the angry genie is out of the oil lamp!

Targeting Texas for landfall, perhaps Ike  won’t grant too many wishes now without the Monkey’s Paw!

Ike is a very large tropical cyclone. Its hurricane force winds extend outward about 200 km from the center and tropical storm force winds extend about 450 km, covering an area of about 640,000 sq km.

Ike’s latest satellite images show a giant clump of white clouds, together with its outer bands, covering most of the 1.6 million sq km area of Gulf of Mexico basin.

Hurricane Ike regional imagery, 2008.09.12 at 08:45UTC. Centerpoint Latitude: 26:54:30N Longitude: 91:31:08W.


Data Elements: Hurricane Ike is located southeast of Galveston, Texas. This system is moving toward the west-northwest near 13 MPH. Maximum sustained winds are near 105 MPH. Hurricane Ike is a large and powerful storm, quite capable of strengthening before landfall early Saturday.
Observation Device: GOES-12 4 km infrared imagery.

Note: As of September 12 – 13:45UTC Image Update, Ike appears to have redeveloped the hurricane eye.

Ike is expected to strengthen to a major hurricane before landfall with sustained wind speeds of at least 178 km/hr, and in all probability the forecast would prove accurate.

However, if Ike fails to strengthen before landfall, it can still cause substantial damage by dumping large amounts of rain, flooding low-lying coastal areas, blowing down trees and road signs, destroying roof structures, doors, windows, curtain walls and mobile homes.

100 mph plus winds expected along the upper-Texas coast by midnight, weather should deteriorate earlier (NOAA)

  • Source: NHC
  • Forecaster: Avila
  • Date and Time: Sept 12, 2008 at 15:00UTC
  • Hurricane Watch Area: from Morgan City Louisiana to Baffin Bay, Texas.  Hurricane conditions are expected to reach the coast in the warning area later Friday.
  • Tropical Storm Warning Area: From south of Baffin Bay to Port Mansfield Texas.  A tropical storm warning is also in effect from east of Morgan City to the Mississippi-Alabama border, including the city of New Orleans and Lake Pontchartrain.
  • Current Location: The center of hurricane Ike was located near latitude 27.2 north, longitude 92.6 west or about 480 km east of Corpus Christi, Texas and about 320 km southeast of Galveston Texas.
  • Category and Wind Speed: Maximum sustained winds remain near 165 km/hr with higher gusts.  Ike is a Category 2A hurricane on the FEWW Hurricane Scale (cat 2 on Saffir-Simpson scale), but could reach the coast as a Category Three, major hurricane.  Stronger winds especially in gusts are likely on high rise buildings.
  • Direction: Ike is moving toward the west-northwest near 19 km/hr. A turn toward the northwest is expected later today, with a turn toward the north expected on Saturday.  On the forecast track, the center of Ike will be very near the upper Texas coast by late Friday or early Saturday. However, because Ike is a very large tropical cyclone, weather will begin to deteriorate along the coastline soon.
  • Extent: Hurricane force winds extend outward up to 195 km from the center, and tropical storm force winds extend outward up to 445 km.
  • Estimated minimum central pressure: 954 mb (28.17 inches).
  • Storm surge flooding: Coastal storm surge flooding of up to 6 meters (20 feet) with a few spots to about 8 meters (25 feet) above normal tide along with large and dangerous battering waves can be expected near and to the east of where the center of Ike makes landfall. The surge extends a greater than usual distance from the center due to the large size of the cyclone. Water levels have already risen by more than 1.5 meter (5 feet) along much of the northwestern gulf coast.
  • Rainfall: Ike is expected to produce rainfall amounts of 12 to 25 cm (5 to 10 inches) over eastern Texas and extreme southwestern Louisiana, with isolated amounts of 38 cm (15 inches) possible.
  • Isolated tornadoes: Isolated tornadoes are possible today over portions of southern Louisiana and extreme southern Mississippi.  Isolated tornadoes are possible tonight over portions of southwestern Louisiana and southeastern Texas.

Dolly Wreaks Havoc Across South Texas

Posted by feww on July 23, 2008

Dolly dropped up to 12 inches (30 cm) of rain in the first few hours of making landfall

Dolly made landfall on South Padre Island, Texas, about 2 p.m. ET, tearing roofs and observation decks off homes, shattering windows and downing power lines. It flooded the streets and sent about 2,500 residents scrambling for safety from wind gusts of about 150 mph.

Texas Gov. Rick Perry declared 14 counties disaster areas prior to Dolly’s arrival. About 1,500 National Guardsmen have been deployed, according to various news bulletins.

In Northern Mexico, about 20,000 people are expected to be evacuated to government shelters according to Eugenio Hernandez, governor of Tamaulipas, Mexico.

It is unclear why the efforts of a certain “hurricane control” company failed so miserably! </sarc>


A boat is blown into the building by Hurricane Dolly in Port Isabel, Texas July 23, 2008. Hurricane Dolly moved inland after tearing into the south Texas coast on Wednesday with 95 mph (150 kph) winds, pouring torrential rain on the U.S.-Mexico border area and threatening floods. Dolly, the second hurricane of the 2008 Atlantic hurricane season, dropped up to 12 inches (30 cm) of rain in the first few hours after coming ashore at the barrier island of South Padre Island, where it ripped off roofs, bent palm trees in half and left thousands of residents without power.

INTENSITY IS ESTIMATED A 75 KNOTS AND A CONTINUED WEAKENING IS
FORECAST AS DOLLY MOVES FARTHER INLAND. THE INTENSITY FORECAST
FOLLOWS CLOSELY THE INLAND DECAY SHIPS MODEL.

DOLLY BEGAN TO MOVE ON A MORE STEADY NORTHWEST TRACK AT ABOUT 7
KNOTS. THE HURRICANE IS NOW LOCATED SOUTH OF A SUBTROPICAL RIDGE
OVER THE WESTERN UNITED STATES…THEREFORE…A GRADUAL TURN TO THE
WEST-NORTHWEST AND WEST IS ANTICIPATED UNTIL DISSIPATION IN ABOUT
48 HOURS.

DOLLY IS A LARGE SLOW MOVING SYSTEM AND CAN CONTINUE TO PRODUCE VERY
HEAVY RAINS DURING THE NEXT DAY OR TWO.
