The official tropical weather thread - 2012

[wagonrunner]

so you mean no rain this weekend?

[firstchoicett]

sky looks clear already in California.

[Hook]

nah, mild wave coming in from Thursday. I'll know the Friday outlook by this evening.

[Soundwave]

sorcery...

[noshownogo]

Looks like the same system from yesterday now heading over Trinidad, seems to be level rain over most of the island throughout today.

what "system"? did you put a "system" there?

[firstchoicett]

Hmmm slight rain falling this morning in California no thunder showers yet .

[noshownogo]

sorry wrong term used, just appears to be the heavy cloud cover I saw from yesterday.

[Hook]

We MUST be careful of the words we choose when it comes to weather and a population that LOVES to panic (and seek every excuse to go home early).
I remember there being a heated discussion with a popular TV weather presenter over his use of the word "thunderstorm" instead of "thundershower", when Trinis latched on to the "storm" and our phones rang off the hook with members of the public asking why we didn't tell them about the storm before

Anyway, there is no system. Just the ITCZ...it never goes away, just oscillates between latitudes, sometimes in patches, sometimes in a more continuous stream.
Looks to be more stratified cloud than anything else, but with the localized heating, there may be one or two moderate/heavy showers and/or thundershowers.
In Piarco we're getting patches of diffused sunlight and then moderate showers with little sky clearing in between.

rain falling down penal

[Duane 3NE 2NR]

Hook!



I know the solid almost vertical line on the map is a tropical wave (not just because it is labelled that). The L marked with an x is a low pressure area on the wave and it is currently at 1010mb which isn't really that terribly low.

But what is the dashed line? a trough? a ridge? detach here? faulty red ink pen?

[redmanjp]

Thats the trop. wave the tv6 weatherman was sayin coming tomorrow evening into Saturday- NHC website doh have nothing though

doh know what d dashed line is

[firstchoicett]

I say I go hit ah Maracas tomorrow but plans might have 2 change .

[Hook]

hard luck Duaneington...saw this like after midnight last night and I'd been drinking, so... but yeah, it's a trough, though not a particularly high amplitude one and by now it's already north of us.

I been looking at the winngrids a short while ago and it looks like we're going to get a surge of moisture in time for the passing of that wave tomorrow (as opposed to the wave last week around this time that came into relatively dry conditions). Hopefully it would have rained out in time for that outdoor rock show in Park Place 2mro night.

[Duane 3NE 2NR]

^ thanks Hooky Hookington!

[Duane 3NE 2NR]

..TROPICAL WAVES...

TROPICAL WAVE EXTENDS FROM 22N21W TO 11N25W MOVING W AT 10 KT. A
1011 MB LOW IS EMBEDDED ON THE WAVE AXIS NEAR THE CAPE VERDE
ISLANDS AT 14N24W. THE SYSTEM IS ALONG THE LEADING EDGE OF A
DEEP LAYER MOISTURE MAXIMUM AS INDICATED ON TOTAL PRECIPITABLE
WATER IMAGERY. THE SYSTEM ALSO COINCIDES WITH A BROAD 700 MB
TROUGH. ISOLATED MODERATE CONVECTION IS S OF THE LOW CENTER FROM
7N-14N BETWEEN 22W-28W. WIDELY SCATTERED MODERATE CONVECTION IS
E OF THE WAVE AXIS ALONG THE COAST OF WEST AFRICA FROM 15N-18N
BETWEEN 15W-19W.

TROPICAL WAVE EXTENDS FROM 19N61W TO 10N61W MOVING W AT 15 KT.
CYCLONIC TURNING IS EVIDENT IN THE LOW-LEVEL CLOUD FIELD IN THE
VICINITY OF THE WAVE AXIS BETWEEN 55W-61W. AN INCREASE OF
TROPICAL RAIN AND SHOWERS ARE NOTED OVER THE LEEWARD AND
WINDWARD ISLANDS E OF 67W.

..
CARIBBEAN SEA...
A TROPICAL WAVE IS OVER THE E CARIBBEAN. ANOTHER TROPICAL WAVE
IS OVER CENTRAL AMERICA AND THE YUCATAN PENINSULA. SEE ABOVE.
ELSEWHERE...A 1008 MB LOW IS CENTERED OVER THE SW CARIBBEAN N OF
PANAMA AT 10N80W. WIDELY SCATTERED MODERATE CONVECTION IS FROM
9N-13N BETWEEN 77W-86W. 15-20 KT TRADEWINDS ARE NOTED BETWEEN
THE TROPICAL WAVES. STRONGEST SURFACE WINDS ARE OVER THE CENTRAL
CARIBBEAN BETWEEN 68W-80W. SCATTERED MODERATE TO STRONG
CONVECTION IS NOTED OVER THE HIGHER ELEVATIONS OF HISPANIOLA...
JAMAICA...AND CUBA. IN THE UPPER LEVELS...AN UPPER LEVEL HIGH IS
CENTERED OVER W CUBA NEAR 22N82W. ANOTHER UPPER LEVEL HIGH IS
CENTERED OVER THE CENTRAL CARIBBEAN NEAR 15N73W. UPPER LEVEL
DIFFLUENCE OVER HISPANIOLA AND E CUBA IS ENHANCING CONVECTION.
