An Atlantic tropical wave worth watching
A large tropical wave near 9N 40W, midway between Africa and the Lesser Antilles Islands, is generating a considerable amount of heavy thunderstorm activity as it moves west to west-northwest at 15 mph. The wave is under about 10 - 15 knots of wind shear, and this morning's QuikSCAT pass showed a large and disorganized region of converging winds in the region, with top winds of 25 mph. There is very little dry air in the vicinity, and conditions appear favorable for some slow development of this wave. None of the computer models develop the wave, but they do show relatively low wind shear along the wave's path for the next five days. The wave should reach the Lesser Antilles Islands by Wednesday.

In the Philippines, Tropical Storm Parma continues to linger offshore the northern tip of the Philippines' Luzon Island, bringing heavy rain. The storm has been blamed for the deaths of 17 people in the Philippines, but has not not had the devastating impact that was earlier feared. Parma's heaviest rains will stay offshore of the Philippines today (Figure 2).
Figure 2. Forecast rain amounts for Parma for the 24-hour period ending at 06 UTC October 5 (2am EDT Monday). This forecast is based on satellite measurements of Parma's current rainfall rate, plus a projection of the storm's path. Four to eight inches of rain (yellow colors) is expected along the extreme northwest tip of Luzon Island. Image credit: NOAA Satellite Services Division.
Super Typhoon Melor hits Cat 5 strength
Super Typhoon Melor has become the second Category 5 tropical cyclone of the year. Melor is expected to recurve to the north pass just south of the coast of Japan later this week.

Grace on stage?
For those not believing in Grace.
The NJ storm never got this kind of appreciation by Dvorak
Sadly, very sadly --I'm thinking it's going to be a COLD one. (El Nino holds hands w/El Norte') Oak Trees are very heavy w/ nuts too BTW.
only good thing is we need a mass killing of all FLEAS - they're outta control with two years of light winter.
I had know about this.... wonder how it would affect the Nuclear Energy Plant in Port. Lucie
Bottle of Pepsi...times 2....check.
Toothpicks to get rid of popcorn remains between teeth...check.
Drama on the blogs...check.
***Reading it....priceless***
For everything else, there's Mastercard.
Nah, it's just cracking up over Grace as we said earlier.
It's working!
(That's what the NHC were doing in naming it.. Ahh, how holistic of them.)

It was named at... 11pm? So 4am over here. (3am GraceTime, anyhow.)
Just over the Azores.
Then fast forward a bit... To when it was named:
Midday today.
It may not have the tropical mechanics (It is waayyyyy out of its comfort zone after all.. it's not even in the subtropics.) but it certainly looks the part.. in Marco-dimensions, anyway. (Macro -> Micro -> Marco, you see.)
Tuesday brings much warmer weather as the warm front moves away from the area bringing in higher humidity creating heat index readings as high as 102.
By time we get to the weekend this will feel like heaven...
Saturday: Cloudy with a 50% chance of rain showers. Low: 65. High: 78. Wind: NE 15mph.
Sunday: Mostly sunny. Low: 62. High: 79. Wind: E 10mph.
Lol. The NWS assures me that the end of the week cold front has a good chance of pushing through here. I hope so. :)

I bet Joe B. will have fun with this one.
They are of the entire world (or at least the half that's visible at any given time) - clearly taken from way out there. These images provide good perspective on the size of a particular storm.
Can someone please direct me to where I can find the Web site that hosts/publishes them?
Many thanks!
But really, why does the warning intensity go so far back???

ANOTHER TROPICAL WAVE ALONG 42W S OF
15N WILL MOVE INTO THE TROPICAL N ATLC ZONE BY TUE. THIS WAVE
HAS MODERATE TO STRONG CONVECTION WITHIN 150 NM OF THE WAVE AXIS
FROM 09N TO 16N AND THE 2344 UTC ASCAT PASS SHOWS WINDS IN THE
20 TO 25 KT RANGE ASSOCIATED WITH THE NORTHERN QUARTER OF THE
WAVE. BUOY 41041 SAW WINDS IN THE 20-25 KT RANGE AND SEAS TO 8
FT AT 0300 UTC. THE MODELS SHOW SOME DEVELOPMENT OF THIS SYSTEM
AS IT APPROACHES A WEAKNESS IN THE SUBTROPICAL RIDGE E OF THE
LESSER ANTILLES AND LIFTS NORTHWARD. THE FORECAST IS CLOSE TO
THE ECMWF...DEVELOPING A 1014 MB SURFACE LOW ALONG THE TROPICAL
WAVE BY TUE NIGHT NEAR 16N55W AND SPLINTERING THIS LOW OFF FROM
THE TROPICAL WAVE AND TRACKING IT NW...PASSING N OF PUERTO RICO
AND INTO THE SW N ATLC ZONE ON FRI. THE PARENT TROPICAL WAVE
WILL CONTINUE W INTO THE CARIBBEAN WED NIGHT THROUGH FRI.
Again the Atlantic Basin covers a wide area and this is within that area; and its fully tropical
It is small, but looking at the loop; no question it deserved a name
GM Surfmom - really sweating that one, filing it just below *falling airplane propeller strike* :O
wu got mail
what size of wave did the USA get from the Samoan Tsunami?
I almost have to agree with the Weather channel with this one.......LOOK at this graphic very close.....with Grace located at 43N 18W not only does this graphic show it could not be tropical with the Temp. but the Min. Central Pressure shows it could not qualify to be Tropical either........I guess they are stretching there values....

Hope it helps. I still can't make heads or tails out of it. :)
Season is still over,

0.6 ft on the pacific coast of us and 1.6 in Hawaii.
From Hawaii247.org
"Hilo recorded a 0.5 foot rise in sea level, on top of about 3-4 foot waves."
Geez grow up

This graphic certainly does not show Tropical Storm force winds......
