Invest 90E in the Eastern Pacific

[Brandon007]

go ahead fact789 say it will become a hurricane

[JonathanBelles]

no thanx

[Brandon007]

hehe come on ROFL

[JonathanBelles]

no, no thats ok

[JonathanBelles]

no, no thats ok

Could someone give me a good definition of INVEST, because I think I know what it is, but I'm not positive.

An area of disturbed weather that a weather forecast agency thinks has a chance of tropical development. They usually update the positions/intensities at least twice a day. The US Navy opens most of them I think, save the Atlantic and EastPac where they defer to TPC most of the time.

I think that with the below explanation you will have a complete idea about what are Invests.

Atlantic(L): North of the equator between N. America and Africa
East Pacific(E): North of the equator between 140W and N. America
Central Pacific(C): North of the equator between 180W and 140W longitude
West Pacific(W): North of the equator between 100E and 180E longitude
Indian Ocean:
(A) North of the equator between Africa and 77E longitude
(B) North of the equator between 77E and 100E longitude
Southern Hemisphere:
(P) South of the equator between 135E and S. America
(S) South of the equator between Africa and 135E longitude
Letter identifiers are assigned to the storm's basin of origin. If a storm passes over a basin boundary, the storm will maintain it's basin of origin letter identifier even though it has entered a new region. For example, storm "Alpha" originates in the Eastern Pacific and is assigned 01E. If it makes its way into the Central Pacific it will still maintain its number and name designation even though it is seen under the Central Pacific header.
The storm number can be an eighty series (80-89), ninety series (90-99), or a number between 1 and 50. Storms seen with a number between 80 and 89 are usually used for testing purposes only. Storms with numbers between 90 and 99 are areas that forecasters use to monitor suspect regions typically with disorganized large-scale convection that has a chance to develop into a more organized system such as a tropical depression. Storms with numbers between 1 and 50 are/were storms that reached tropical storm strength or higher.
The naming convention after the number/basin pair can be called INVEST, NONAME, or assigned name. All storms will start with an INVEST name. When the system becomes a tropical storm this name will change to either NONAME or assigned name. NONAME is assigned to storms which do not have an official assigned name yet. Assigned names are given to tropical storms according to the World Meteorological Organization (WMO). Typically, storms that form in the Indian Ocean north of the equator will have NONAME. There are a few occasions where a tropical storm name will have an INVEST or a ONE, TWO,... following the number/basin pair. This name is only temporary and typically lasts for only a couple of hours. This is caused by the timing of the position updates generated by the Automated Tropical Cyclone Forecasting (ATCF) system and when forecasters determine that the system has become a tropical storm.

dose this mean TD.1 the first one of the season forming soon??????????

Could be...

S OF 15N...
AFOREMENTIONED UPPER LEVEL TROUGH EXTENDING SW FROM CENTRAL
MEXICO NEAR 17N96W PENETRATES DEEP INTO THE TROPICAL PACIFIC
WATERS AS A CYCLONIC SHEAR AXIS REACHING 10N110W. CONFLUENT
FLOW POLEWARD OF THE TROUGH/SHEAR AXIS IS GENERATING MODERATE
SUBSIDENCE N OF THE ITCZ BETWEEN 102W-125W. AS A RESULT...ITCZ
CONVECTION IS SUPPRESSED S OF 10N IN THIS REGION. E OF
105W...THE FLOW ALOFT BECOMES INCREASING DIVERGENT IN
ASSOCIATION WITH A RIDGING IN THE MIDDLE TO UPPER LEVELS. ITCZ
CONVECTION REMAINS QUITE ACTIVE FROM 90W-105W ESPECIALLY IN THE
VICINITY OF A 1007 MB LOW LOCATED NEAR 9N98W. SATELLITE IMAGERY
INDICATES THAT CONVECTION NEAR THE LOW CENTER HAS BEEN STEADILY
INCREASING OVER THE LAST 24 HOURS BUT REMAINS DISORGANIZED. AS
SUCH...IMMEDIATE DEVELOPMENT IS NOT EXPECTED BUT SLOW
STRENGTHENING OF THE LOW IS POSSIBLE AS IT MOVES WESTWARD AT
5-10 KT DURING THE NEXT DAY OR SO.

Season starts in 23 minutes UTC

[JonathanBelles]

java wont let me into the chatroom, does anyone know what a proxy setting is, and how to fix it?

[CHRISTY]

Here's an IR loop on our new INVEST!

[Matt-hurricanewatcher]

Looks like it has alot of southwestly shear.

[Epsilon_Fan]

nice... we finally have an invest, at least most of the EPAC storms are fish!

[CHRISTY]

Looks like it has alot of southwestly shear.

yea a agree matt!it looks elongated.

Storms with numbers between 1 and 50 are/were storms that reached tropical storm strength or higher.

Everything's OK except this comment. Systems get a sequential number 1-50 when they become a tropical or subtropical cyclone (i.e., depression or higher), not storm strength or higher.

[Jim Cantore]

I say be becomes Aletta, just to go out on a limb

ANOTHER NIGHT, ANOTHER POOF!!!
