Typhoon Parma May Not Be Done With Philippines; Typhoon Melor Still To Come

Typhoon Parma Forecast Track 00Z 10.04.09

While Typhoon Parma made its way through the Philippines, it took out crops and infrastructure and produced damage in some of the towns and cities, but so far only 3 have been reported killed.  Some reports around the world claim that the storm is moving toward Taiwan.  Taiwan has even issued warnings and made evacuations.  But, I’m not so sure that Parma is done with the Philippines.  A look at the Western Pacific Water Vapor Imagery Loop shows appears to show an eye reforming.  The official forecast from the Joint Typhoon Warning Center has been all over the place, indicating that there are lots and lots of variables.  Previously, we’ve seen the long term track toward Taiwan, then to the northeast, then having it become quasi stationary just northwest of Manila, then having it move north-northwest before looping back around in the wake of Typhoon Melor (JTWC Discussion) and out to the northeast.

Typhoon Melor Forecast Track 00Z 10.04.09

The new forecast reflects the fact that the storm has moved offshore to the north of the island and has been moving west or west northwest very slowly.  The idea is that the storm will meander offshore of the northwestern coast of the Philippines.  The boys at the JTWC acknowledge that the forecast is very difficult and acknowledge that there are other plausible scenarios. Its extremely complicated because there is a typhoon to the east, a storm to the west, a ridge to the north and somewhere in between, there is a trof.  While I have no idea where its going to go, I think that it is entirely possible that the Philippines is not done with Parma.  If you look at the US Navy NOGAPS model, you see that at 18Z Oct 5,the storm is centered just west of Manila…offshore.  That would bring rain to the islands.  The GFS has the storm right over Manila at the same time.  The NOGAPS brings Parma right over the top of Manila at 18Z on the 6th.

There are other solutions out there but most of them are not too good for the Philippines.  In fact, if the GFS solution verifies, which is probably won’t completely, then Japan would get brushed by Typhoon Melor and then 3 days later get brushed by Typhoon Parma..both running right along the mouth of Tokyo Bay.  But…these storms have not been playing ball and all options remain on the table.

1. FOR METEOROLOGISTS.
2. 12 HOUR SUMMARY AND ANALYSIS.
    A. TYPHOON 19W (PARMA), LOCATED APPROXIMATELY 250 NM NORTH OF

NOGAPS 6Z Oct 7 Parma Over Manila

NOGAPS 6Z Oct 7 Parma Over Manila

MANILA, PHILIPPINES, HAS TRACKED WESTWARD AT 07 KNOTS OVER
THE PAST SIX HOURS. THE SYSTEM HAS MOVED BACK OVER WATER IN THE
STRAIT OF LUZON AND HAS STARTED TO REGAIN ORGANIZATION AS SEEN IN
RECENT ANIMATED MULTISPECTRAL IMAGERY. A 032224Z SSMI 37GHZ IMAGE
SHOWS THE LOW LEVEL WITH GOOD STRUCTURE AND AN EYE-LIKE FEATURE OVER
WATER TO THE NORTHWEST OF LUZON. THE SYSTEM IS LOCATED UNDER AN
UPPER-LEVEL RIDGE AXIS THAT IS PROVIDING EXCELLENT WESTWARD AND
EQUATORWARD OUTFLOW. THE SYSTEM IS IN A RELATIVELY WEAK STEERING
ENVIRONMENT UNDER THE INFLUENCES OF THE SUBTROPICAL RIDGE (STR)
CENTER LOCATED TO THE NORTHEAST.
3.   FORECAST REASONING
    A. THE FORECAST PHILOSOPHY HAS CHANGED SIGNIFICANTLY SINCE THE
PREVIOUS PROGNOSTIC REASONING BULLETIN. THE FORECAST HAS THE STR
OVER SOUTHERN CHINA BECOMING THE PREDOMINATE STEERING INFLUENCE ON
THE SYSTEM AFTER TAU 72 AND TRACKING THE 19W INTO THE SOUTH CHINA
SEA.

W. Pacific IR Satellite-Parma and Melor are easily found

W. Pacific IR Satellite-Parma and Melor are easily found

    B. THE SYSTEM WILL SLOWLY DRIFT NORTHWESTWARD INTO THE LUZON
STRAIT AS THE STR TO THE NORTHEAST, LOCATED SOUTH OF JAPAN, ERODES
IN ADVANCE OF A MIDLATITUDE TROUGH. THIS WILL LEAVE TY 19W IN A VERY
WEAK STEERING ENVIRONMENT, REMOVED FROM THE INFLUENCES OF THE STR TO
THE NORTHEAST AND THE STR LOCATED TO THE NORTHWEST OVER SOUTHERN
CHINA. DUE TO THE LACK OF STEERING FLOW, THE SYSTEM WILL REMAIN
QUASI-STATIONARY THROUGH TAU 72 AND THE GENERALLY FAVORABLE
ENVIRONMENTAL CONDITIONS WILL FACILITATE FURTHER INTENSIFICATION.
HOWEVER, INTENSIFICATION WILL BE LIMITED DUE TO UPWELLING OF COOLER
WATER, WHICH IS TYPICAL OF SLOW-MOVING SYSTEMS. MODEL GUIDANCE SHOWS
VERY ERRATIC MOVEMENT OF THE SYSTEM THROUGH TAU 72.  THIS IS
INDICATIVE OF A SYSTEM WITH WEAK STEERING INFLUENCES THAT IS
EXPECTED TO MEANDER AIMLESSLY. THE ONLY MODEL THAT DOES NOT SHOW
THIS MOTION IS GFS, WHICH SUPPORTS STRENGTHENING OF THE STR TO THE
EAST AND A SHARP TURN AND ACCELERATION TO THE NORTHEAST BEHIND TY
20W. A TURN TO THE NORTHEAST IS STILL A VIABLE ALTERNATIVE TRACK,
ESPECIALLY IF THERE IS BINARY INTERACTION WITH THE APPROACHING TY
20W FROM THE EAST, BUT BECOMING MORE UNLIKELY AS 19W CONTINUES TO
TRACK NORTHWESTWARD.
    C. AFTER TAU 72, THE STR OVER CHINA IS EXPECTED TO BUILD AFTER
THE PASSAGE OF A ZONAL TROUGH IN THE MIDLATITUDES. AS IT BUILDS, IT
WILL IMPART A WEAK INFLUENCE ON 19W THAT WILL SLOWLY DRAG THE SYSTEM
TO THE WEST INTO THE SOUTH CHINA SEA. AS THE SYSTEM MOVES TO THE
WEST, AVAILABLE OCEAN HEAT CONTENT WILL DECREASE AND NOT BE ABLE TO
SUPPORT A SLOW MOVING TYPHOON, AND INTENSITY WILL START TO SLOWLY
DECREASE IN THE LATE PERIOD. MODEL GUIDANCE IS IN POOR AGREEMENT
AFTER TAU 72 AS TO THE ACTUAL TRACK OF THE SYSTEM. ECMWF, TCLPS AND
JGSM  TAKE THE SYSTEM ON A MORE SOUTHWESTERLY TRACK AND EGRR AND
GFDN TAKE THE STORM ON A WESTERLY TRACK. NOGAPS KEEPS THE SYSTEM
QUASI-STATIONARY THROUGH THE FORECAST PERIOD.//

  1. do you have live satellite update for typhoon parma and typhoon melor?from NASA perhaps?

    wanna learn more about it. been tracking this typhoons( ketsana, parma and melor) since last week.

  2. where is the eye located?

  3. WE WILL BE STILL AND KNOW THAT GOD IS MUCH POWERFUL THAN THESE TYPHOONS. GOD BLESS THE PHILIPPINES!

  4. If you want to know exactly at given time, the best way to find it will be to go to the link with the water vapor imagery loop. You will be able to see it there the easiest if there is an eye. From the time that I posted this blog at about 1AM on Sunday EDT, the drift to the west turned into a drift to the north. This guy is difficult to forecast, as you can tell by the changing official forecasts. Also, if you click on the forecast track map, it will give you the most recent information

  5. If you click on the links to the loops, it will give you the most recent images.

  6. furry and intensity of these storms are due to global warming which is not due to human activity. but only due the ongoing sociology of corporate capitalism rooted in the Adam Smithan sociology. which is constitutionalised in the so called free and democratic system. Until and unless the world human community adopts the Nature -Human Centric Sociology , the future of human community is not bright.

  7. The storms that struck the Philippines were not overtly strong. The frequency or intensity of tropical cyclones has not largely changed in recorded history. There continues to be a flux from year to year or decade to decade. Some researchers argue that global warming would actually decrease the number of tropical cyclones. I would like to see some substantiation of your comments. Thanx for writing.
