Evening TraumaBoyy. Hoping your night is quiet and full of coffee and donut breaks!
I was expecting a cat 2, perhaps high end cat 2 if it stayed further away from land. However, Beatrice has had plans of her own and has been hugging the coastline for a while now, and has come increasingly closer to land. At least 1/3rd of the storm is over land now. Not to mention the land is very rugged and mountainous. Additionally, this system is fairly large and larger systems can take a while to get well organized, as noted by the ragged looking core. So it makes sense that this system hasn't really intensified in the last 6hrs.
Since the storm is expected to move over cooler SSTs, a drier and stabler air mass, as well as increased interaction with land, I don't expect this storm to become much stronger. If it continues on a more eastern or northern course, riding the coastline, then I'd say its reached its peak
For Beatriz to become annular, the intense convection around the eye would have to become near symmetrical, spiral banding would have to become minimal to non existent, the eye would need to become better defined and clear out.
Simply put, Beatriz is far from annular. And due to its extremely close proximity to land and the presence of rough mountainous terrain over land, as well as its forecasted track over cooler SSTs and a more stable and dry air mass within the next 2 days, I highly doubt this will become an annular hurricane.
Staying humble is the biggest challenge in this field.

The National Weather Service in San Angelo has issued a
* Tornado Warning for...
northern Coleman County in north central Texas...
* until 330 am CDT
* at 245 am CDT...a severe thunderstorm capable of producing a
tornado was 4 miles east of Glen Cove...or 10 miles west of
Coleman...moving southeast at 25 mph
Probably the best case scenario for Mexico right now. Most of Mexico has been in a Texas-style drought.
"About 40 percent of Mexico's territory has been experiencing the worst drought in seven decades, President Felipe Calderon said. Mexico experienced its second worst drought in 60 years in 2009, while 2010 was the rainiest year on record...
There are areas in Mexico where it has not rained since September..."
As is, HurricaneBeatriz is reported to be dropping precipitation as far east as MexicoCity... as well as wetting the formerly dry air flowing into the Gulf of Campeche. Which is good news inregard to future tropical development leading toward rainfall for both Texas and easternMexico.
In the near term, the best case scenario would be for TropicalStormBeatriz to turn northnorthwestward to continue following the coastline up through the center of the Gulf of California (Sea of Cortez) all the way to Yuma*Arizona, then head east as it breaks up.
Not likely given the NHC's predicted path westward (or given the SSTs and atmospheric conditions), but one can always wishcast.

HURRICANE BEATRIZ DISCUSSION NUMBER 8
NWS NATIONAL HURRICANE CENTER MIAMI FL EP022011
200 AM PDT TUE JUN 21 2011
RECENT MICROWAVE IMAGERY SHOWS THAT BEATRIZ HAS DEVELOPED A
WELL-DEFINED 20-25 N MI WIDE EYE...A FEATURE THAT ALSO MADE A
SHORT-LIVED APPEARANCE IN INFRARED IMAGERY. SATELLITE INTENSITY
ESTIMATES HAVE INCREASED TO 90 KT FROM SAB AND 77 KT FROM
TAFB...WITH AUTOMATED ESTIMATES FROM THE UNIVERSITY OF WISCONSIN OF
90 KT. BASED ON THIS...THE INITIAL INTENSITY IS RAISED TO 80 KT...
AND THIS COULD BE CONSERVATIVE. CLOUD TOPS IN THE EYEWALL ARE
COLDER THAN -80C...AND THE CIRRUS OUTFLOW IS GOOD IN ALL
DIRECTIONS.
THE INITIAL MOTION IS NOW 330/10. BEATRIZ IS HEADING FOR A WEAKNESS
IN THE SUBTROPICAL RIDGE CAUSED BY A LARGE DEEP-LAYER TROUGH OVER
THE CENTRAL UNITED STATES. THE LARGE-SCALE MODELS ARE IN GOOD
AGREEMENT THAT THIS TROUGH SHOULD MOVE EASTWARD DURING THE NEXT FEW
DAYS...WITH A MID-LEVEL RIDGE DEVELOPING NORTH OF BEATRIZ. THIS
EVOLUTION SHOULD GRADUALLY CAUSE THE CYCLONE TO TURN TOWARD THE
LEFT...WITH A GENERALLY WESTWARD TRACK EXPECTED BY 48 HR.
HOWEVER...BEFORE THIS TURN OCCURS...THE CENTER IS LIKELY TO PASS
OVER OR NEAR THE COAST OF MEXICO BETWEEN MANZANILLO AND CABO
CORRIENTES. THE NEW FORECAST TRACK IS SIMILAR TO THE PREVIOUS
TRACK...BUT IS ADJUSTED A LITTLE TO THE NORTH BASED ON THE CURRENT
POSITION AND MOTION.
THERE IS A CHANCE FOR ADDITIONAL STRENGTHENING THIS MORNING...AND
THE MAXIMUM WINDS COULD REACH 85-90 KT BEFORE THE CENTER INTERACTS
WITH THE COAST OF MEXICO. AFTER THAT...A COMBINATION OF LAND
INTERACTION AND A FORECAST TRACK OVER COLDER SEA SURFACE
TEMPERATURES SHOULD CAUSE BEATRIZ TO WEAKEN. THE NEW INTENSITY
FORECAST ASSUMES THAT LAND INTERACTION WILL NOT CAUSE A RAPID
DISINTEGRATION...WITH THE CYCLONE GRADUALLY DYING OUT OVER THE
COLDER WATER WEST OF CABO CORRIENTES. AN ALTERNATIVE SCENARIO IS
THAT THE CYCLONE CIRCULATION IS SERIOUSLY DISRUPTED BY THE MOUNTAINS
OF WESTERN MEXICO. IF THIS OCCURS...BEATRIZ WOULD WEAKEN FASTER
AND DISSIPATE EARLIER THAN CURRENTLY FORECAST.

FORECASTER BEVEN
I was already watching that LPA. looks interesting.
I don't know about that. Meet Hurricane Rosa 1994. I remember this flood. We were in the process of moving into our brand new house. It was a mess to say the least! Rita moved us out 11 years later. Sigh. ;)
United States
Rosa sent moisture into the United States, which, in combination with humidity drawn north from the Gulf of Mexico, caused heavy thunderstorms and flooding in parts of thirty eight Texas counties on October 15 to 19. The flooding was worst around the San Jacinto and Trinity River basins, and in coastal areas. Rainfall totals ranged from 8 in (200 mm) to more than 28 in (710 mm).[14] The rain levels caused 100-year floods at nineteen stations. Several records were broken, some of which had stood since 1940. In the case of the Lavaca River near Edna, it broke a record set in 1936.[15] The flooding destroyed 3069 homes, heavily damaged 6560, and damaged 6148 others. Railbeds and roads sustained damage, while broken gas and oil pipelines caused spills and environmental damage in the Lower San Jacinto River and Galveston Bay. Twenty-two people died due to effects from the storm. In total, the flooding in southeastern Texas caused 700 million (1995 USD) in damage.[14] On October 18, the Federal Emergency Management Agency (FEMA) declared the worst-affected areas a disaster area.[16] After the declaration, FEMA received 26,000 applications for disaster assistance and approved 54 million (1995 USD) in aid.[14]

Beatriz is not even close to an annular storm
It's not becoming annular. The spiral rainbands should be gone.
I woke up to thunder, not a common thing in the early morning. A wave is moving south of PR combining with a shortwave trough causing the inestability.
By the way,13.35 inches have fallen in June, to keep adding up the new record.
Maintaining strength, maybe even weakening.
Wait, what?
Don't mind at all.....been buzy savin the world!! How is the hurricanader doin??
Look at the structure, look at how the CDO has become elongated from what it was. Here's an IR to prove that. Heavy land interaction.
wow,nice...
i'm at 10 inches,expecting 3-4 over the next 2-3 days.
