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

Typhoon FITOW Chased by Cyclone DANAS

DANAS has intensified to a typhoon force packing sustained winds of about 125km/hr. FIRE-EARTH models show that DANAS could potentially influence its predecessor, typhoon FITOW,  effectively pinwheeling the earlier typhoon [“Fujiwhara Effect,”] if the former stalls, or becomes quasi stationary again.

China issues highest warning as Typhoon FITOW nears

China’s meteorological agency on Saturday issued a “Red Alert,” the country’s highest in its weather warning system, as Typhoon FITOW neared its southeast coast.

FITOW was located approximately 550km east of Taipei, according to FIRE-EARTH projections, tracking WNW at about 13km/hr, generating maximum significant wave heights of about 12 meters.

FITOW as of 9:00UTC on October 5, 2013

  • Location: near 27.0ºN,119.3ºE
  • Movement and speed: WNW  at 13km/hr
  • Max sustained winds: 175km/hr
  • Max wind gusts: 210km/hr

The typhoon is expected to move NW at a speed of about 15 km per hour, and would likely strengthen slightly, said China’s National Meteorological Center (NMC).

“FITOW is likely to make landfall in the coastal areas between central Zhejiang Province and northern Fujian Province between Sunday night and Monday morning,” said NMC.

“The center said it is unusual for a typhoon to make landfall in southeast China in October, urging local authorities and residents to raise their alerts and closely follow relevant information,” said a report.

China’s maritime authorities have also issued an “Orange Alert,” their second highest alert level, for coastal storm surges.

Could Typhoon Melor Drag Parma Back to Philippines?

Posted by feww on October 5, 2009

Typhoon Melor may be heading toward Kanto region, Japan

Barring  a big surprise or last-minute change of heart, typhoon Melor will only briefly enter the Philippines territory late Monday (local time), exiting mostly uneventfully by early Tuesday.

The very slow moving storm Parma to the WNW of Melor loitering in NW Luzon and southern tip of Taiwan region could be dragged back to Luzon, as Melor heads NNW towards Japan. Note Melor’s well-defined eye and
its near-perfect symmetry.

Melor is not expected to impact Philippines directly, but it is controlling the movement of typhoon Parma, which is moving west very slowly as it passes over northern Luzon.

The two typhoons  are interacting, somewhat pinwheeling [“Fujiwhara Effect,”] with Melor packing more powerful winds being the driver, as Parma weakens. In fact, it is possible that Melor could drag Parma back on to Luzon, at least temporarily.

Melor spared Guam and Saipan over the weekend, with NWS in Guam reporting gusts of up to 38 mph and little rain as Melor moved north away from the island Saturday night.
