.UPDATE...THE MARCH OF THE LOW LEVEL DISTURBANCE ACROSS THE
WINDWARD ISLANDS AND INTO THE NORTHEAST CARIBBEAN AT ABOUT 14
KNOTS WAS PUNCTUATED BY A STRONG EMISSION FROM MOUNT MONTSERRAT.
PILOTS REPORTED AN ASH PLUME REACHING FLIGHT LEVEL 550. SATELLITE
PICTURES ALSO REVEALED A PLUME SPREADING OUTWARD IN ALL DIRECTIONS
FROM THE MOUNTAIN WITH CLOUD TOP TEMPERATURES NEAR -76 DEG
CELSIUS...AND ASH WAS BOTH STRONG ENOUGH AND HIGH ENOUGH TO BE
SEEN ON SAN JUANS DOPPLER RADAR IN CAYEY SOME 238 NM AWAY. VISIBLE
PICTURES CONTINUE TO INDICATE SOME EMISSIONS MOVING OFF TO THE
WEST...BUT THE LARGEST EMISSION HAS MOVED OFF THE ISLAND WITH THE
UPPER LEVEL FLOW AND IS MOVING WEST SOUTHWEST TO SOUTHWEST. VERY
LITTLE OF THIS ASH CLOUD WILL GRAZE THE SOUTHEAST CORNER OF OUR
FORECAST AREA.


The above is an updated AFD from the NWS in San Juan about this eruption.

[msbee]

in the link I posted one of the updates said the ash will be moving South west and will be hitting South America.
FORECAST TO REACH THE COAST OF VENEZUELA IN 12
HOURS AND SPREAD SOUTHWEST INTO NORTHEASTERN
COLOMBIA IN 18 HOURS. ...TURK

LOL...Mount Monserrat? The other duty met this morning used to be at San Juan...he can't stop shaking his head.

[MiamiensisWx]

BEAR WATCH!



I couldn't resist!

Lol yes now I saw it as I didn't earlier.Tony that was Snell.

[HURAKAN]

I just updated the Caribbean image for tormenta.net and it really looks like a flare up.

[msbee]

What in the world does bear watch have to do with a volcano erupting in the Caribbean?

[MiamiensisWx]

I was just kidding since it looked like a flare-up of convection on some imagery. Sorry for sounding dumb...

[msbee]

no problem
I thought I was missing the point.

[MiamiensisWx]

OK, msbee! Sorry for sounding like I was -removed-.



The plume even shows up on the imagery on the main site... click here.

[msbee]

-removed-? no, I didn't think you weres doing that.
unless you were -removed- for bears
yes, the plume shows up well there. and it looks like it is spreading.
thankfully it is going away from the islands.

[HURAKAN]

I was trying to find more information but still Google and Yahoo don't have anything on the story.

[bvigal]

I am so HAPPY to say, OSEI has grabbed pic of this!! Here's the link:

It is a joke from last season, a play on the words bears watching, which was used quite a bit last year.

The latest advisory about the eruption.

[cycloneye]

Latest Graphic forecast of ash



Above is the latest graphic forecsat of the ash and it looks like part of it will pass very close to the South Coast of Puerto Rico.

[caribepr]

We were all speculating about an eruption yesterday morning because of the serious haze over us, eye irritations etc. And not enough wind to move it along. Now I know why! (I think my contacts are developing ash pitting).
