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

UPDATE 2: Tropical Cyclone Laurence (06S)

Posted by feww on December 16, 2009

TC Laurence Intensifies to 167 km Sustained Winds

Active Tropical Cyclone in Southern Hemisphere

  • Date Time: December 16 09:00 UTC
  • Approximate Position: 16.3ºS, 124.2ºE
  • Location:  Located approximately 440 nmi northeast of Port Hedland, Australia
  • Movement: Has been tracking 185 degrees  at 08  knots during  the past six hours.
  • Max Sustained Winds:  075 knots, Gusts 090 knots [compared with winds of 35 kt and gusts of 45 kt 48 hrs ago; and 075 kt,   24 hors ago]
  • Max Significant Wave Heights:  Laurence is now located over land.

Based on the current forecast track, the system is now expected to move further inland and dissipate within the next 60- 72 hours. ALL but two models agree.

Remarks by BOM:

  • Severe Tropical Cyclone Laurence is a small but very intense tropical cyclone having VERY DESTRUCTIVE WINDS with gusts to 260 km/h .
  • Laurence is expected to weaken overnight IF it  moves  in a generally southerly direction towards Derby.
  • HEAVY RAIN is expected to continue over the north and west Kimberley. Daily rainfall totals in excess of 100mm are possible near the coast with totals decreasing further inland.
