DESPITE THE FACT THAT GRACE IS MOVING OVER VERY COLD WATERS...AN
AMSU PASS FROM EARLIER TODAY STILL SHOWS THE PRESENCE OF A MODERATE
TO DEEP WARM CORE IN ASSOCIATION WITH THE CYCLONE.

:eek:

whats the story with these ex hurricanes and ex tropical storms making a beeline for ireland lately.

not that im complaining.

i think grace is on her last legs now before shes fully absorbed into that front .PITY


but she was def impressive earlier approaching us

The latest tropical storm in the Atlantic Ocean may have escaped the notice of most when it formed just before midnight last night so far north and east in the Atlantic, away from where forecasters usually look for forming storms. However, NASA's Aqua satellite and forecasters in the Azores Islands, Portugal and Ireland are watching it closely.


Grace came together quickly and her winds were near 65 mph soon after formation. Very early this morning those sustained winds peaked at 70 mph, but fell back to 65 mph. Grace's existence will be short-lived as she's expected to merge with another low pressure area.

It was late last night, October 4 at around 11 p.m. EDT, when Tropical Storm Grace formed about 420 miles northeast of the Azores, near 41.2 North and 20.3 West. By 5 a.m. today, October 5, was speeding north-northeast between the Azores and the British Isles.

Grace had moved to a position about 575 miles southwest of Cork Ireland, and about 590 miles northwest of Lisbon, Portugal near 45.4 North and 16.4 West. Her maximum sustained winds were near 65 mph, and she was speeding northeast near 31 mph. Estimated minimum central pressure is 990 millibars.

NASA's Aqua satellite AIRS instrument captured an infrared image of Grace's clouds on October 4 at 10:17 a.m. EDT more than 12 hours before she came together as a tropical storm. In the infrared imagery, which measures cloud top temperatures, there were some strong areas of convection, but the storm didn't yet have the signature appearance of a tropical storm. However, the storm quickly organized.

AIRS infrared imagery measures temperatures in the clouds, and found a few of the highest thunderstorm cloud tops were cold as -63 Fahrenheit, indicating some isolated strong convection even before the storm came together.

Grace is expected to be absorbed by a large non-tropical low pressure area over the northeastern Atlantic during the day sometime tomorrow and bring rainfall to Ireland.

Should we be expecting stormy weather in Ireland over the next day or so?

AMAZING GRACE,just look at that eye still this morning.

The eye is still visible - that must be a record for a tropical storm so far north and close to our shores...

Redsunset

she looks sure to hit land skirting south cork ,waterford kilkenny and wexford,possibly affecting south laois and carlow.could be interesting rain amounts and extra wind as the eye passes.exciting stuff

yansnow

look quite interesting the eye of grace is reforming due to moisture pushing from the south so she might intensify a bit more before hitting south cork some heavy even torrential rain in the south with a few gust around the eye of the tropical storm..

Keep that image and other ones for posterity. Grace isn't a record breaking storm or anything like that, but to see a storm 'eye' and characteristics so close to Ireland is a very rare event. Will be interesting to see if she makes actual landfall and if her 'eyewall' holds shape.

Redsunset

i think shes losing steam and getting pushed slighty south from the front but i could be wrong.but she deff doin her best not to be bullied by it

yansnow

even met is forcasting potentially heavy rain!!!!quite interesting

Redsunset

the end is near,its tracked a bit too much to the south.precip will linger in the very south east but its game over.very enjoyable tho.one for the books.

am interested to know how it affects wales and england head on

Deep Easterly

Some 24hr rainfall totals up to 7pm this evening from main Met Eireann synoptic stations:

Johnstown Castle: 46mm
Cork Airport: 42mm
Valentia: 35mm
Roaches Point: 34mm
Oak Park: 27mm
Casement: 23mm

Dry (or drier) as expected in the NW half of the country, with falls of between 0.1mm (Claremorris) and 3.3mm (Malin Head).

No doubt higher totals were recorded at minor stations thoughout the South today.
