Hurricane Beatriz slams into Mexico; heavy rains, tornadoes hit the Midwest

Hurricane Beatriz plowed into the Pacific coast of Mexico near La Fortuna this morning as a Category 1 hurricane with 90 mph winds, bringing very heavy rains and mudslides to a 200-mile stretch of coast. Acapulco reported 5.20" of rain yesterday, and one injury due to a falling free. Hurricane-force winds extend outwards 25 miles from the center of Beatriz, and these winds are likely to cause moderate damage along a 200-mile stretch of the Mexican coast today as the storm moves northwestwards towards Cabo Corrientes. However, the primary threat from the storm will be heavy rain, and the expected rains of 6 - 12" are likely to cause very dangerous flooding and mudslides today and Wednesday morning. Satellite loops reveal that Beatriz weakened significantly over the past few hours, once the eye moved over land. The mountainous terrain of coastal Mexico will continue to tear up the storm today, and Beatriz will likely be a weak tropical storm by the time it moves back out to sea on Wednesday.

Tornadoes, heavy rain slam the Midwest
Severe thunderstorms rumbled through a wide section of the Midwest yesterday, generating numerous tornadoes, baseball-sized hail, and heavy flooding rains. The storm also brought heavy snow to the mountains of Colorado above 9,500 feet, an unusual occurrence for so late in June. NOAA's Storm Prediction Center logged 43 preliminary tornado reports yesterday in Nebraska, Kansas, Iowa, Texas, and North Dakota. The tornadoes mostly avoided populated areas, and only sporadic damage was reported. Perhaps the most significant impact of the storm was the large area of 1 - 4 inches of rain it dropped on Nebraska and South Dakota. This rain will run off into the Missouri River, further aggravating the flooding that has breached two levees and overtopped two other levees in the past week. The large, slow-moving low pressure system responsible for the rains and severe weather will bring additional heavy rains of 1 - 3 inches over portions of the Missouri River watershed today, and will touch off a new round of severe weather today and Wednesday as the storm progresses slowly eastwards. However, the Storm Prediction Center is issuing only their "Slight Risk" forecast for severe weather for both days.

Quoting Jedkins01:
If you are in Michigan watch out, PWAT's are well above normal between 1.6 and 1.8 inches ahead of those storms and dewpoints in the low 70's, this will lead to very high rainfall rates for that far north, thunderstorm cores could contain 2 to 3 inch per hour rain rates, which will easily cause flooding because the ground is not designed for tropical rainfall up there.


Are they at risk for severe weather ie hail tornados

Shary?

Danny had some interaction with an upper level trough during his creation (but was a tropical wave).

Grace in 2009 of course was none of those three, coming from an extratropical cyclone or some sort (Laura in 2008 was also in this category, I think).


I think Shary was the result of a disturbance interacting with an ULL, I'm just basing that off pure memory.

I have a spot on the side of the house where the roof and the garage's roof make a funnel. I had to had rocks the size of throw pillows at the "impact point" to keep from the stream digging a cavern in the yard during rainy season. The hard part would be dredging the roof shingle "gravel" out of the bottom of the barrel.

A neighbor told me Sam's Club had rain barrels for $40, which is less than half the price I saw last year, but no idea how big they are.

It never ceases to amaze me on how fast Grace developed. This is the 8:00 PM EDT TWO on October 4, 2009. What would become Grace was only at Less than 30%. In a special TWO at 9:05 PM EDT on October 4, it was at Higher than 50%. Then at the 11 PM AST advisory, Grace was at 65 mph.

Correct, but if that moisture we are reading over Central America does start developing, would that be what the CMC is hitting on then? We have two different systems apparently, NOGAPS hitting on that bomb over the Gulf and the one that becomes Arlene as well.

Yes, Grace came from a large extratropical cyclone that came from a Cold Front. This is the same way that Tropical Storm Laura of 2008 formed also.

One thing I've kinda noticed is the lack of trough split cyclones the last few years. I think the last time we had a named storm that developed from a trough instead of monsoonal or Cape Verde was Edouard in 2008, and TD5 in 2010 was also a trough split but didn't become a named system.

Teddy,

If Beatriz fell apart sooner than the models forecasted, thus the moisture that we are seeing doing the cross continent movement could be what they are forming in the Bay of Campeche. However it would be forming earlier than expected.

You can also say that fall has gotten off to much earlier start in the US the last two years, increasing the frequency and strength of troughs during the peak of the season. Could this be the reason why its been so quiet here since 2007. Don't know, but its possibility.

You just contradicted yourself. There is no correlation between this years storms that form and the fact that we haven't had a landfalling hurricane here in the US since 2008. Hugo hit here in Charleston in 1989 and it'll be 22 years this September. Yes, another hurricane will hit Charleston some day, but it's a 50/50 chance every year. If we get hit this year, it doesn't lower the chance that we get hit in 2012.

You are right - We cannot tell what it is going to be like in terms of landfalls on the USA this early in the season. BUT, several factors point to an active landfall year, which makes me believe that there will indeed be several USA landfalls.

I am not so sure. The 2008 season, one of our analogue years, had 6 tropical cyclone (TS and hurricane) landfalls. Another analogue year, 1999, had 5 tropical cyclone landfalls. The 1996 season, another analogue year, had 4 tropical cyclone landfalls. To top of this post, 1955, one of our analogue years, featured 5 tropical cyclone landfalls.

So in sum, there is consistency with multiple tropical cyclone landfalls on the USA for this season.

Ike had surge comparable to a low end Category 5.

And this is why the folks smarter than me, are constantly argueing for a better ranking/rating system for hurricanes. Yes, Cat 3 is considered a major. Ike was bad, no doubt about it. But it was no Andrew or Ivan, which I thought by your mention of Cat5, you were implying. Ike never got itself all wound up good. It was too big.

It is like was just stated, there's a 50/50 chance of landfalls. Last year's setup was based on timing, and we almost got walloped by a Category 4 just by a hundred miles or so, Earl. We're in a 5 year drought of major hurricanes hitting the United States, and 2 year drought for hurricanes actually striking the US too, we're going to run out of luck eventually. Neutral years favor multiple US landfalls, La Nina years like 2007 & 2010 don't have as many US landfalls as years like 2005 and 2008 do.

Ike's surge damage was mostly due to it's size, and the area where the water piled into. The water had no where to go.

Land Ike on the east coast of Fla, there's have been little to no surge like what it had.

You're spray-painting apples and calling them oranges.


I said in most regards Ike was a major hurricane, BESIDES Ike was a 110 mph hurricane at landfall, the threshold for a Category 3 is 111, are you honestly going to tell me that's going to make much of a difference with wind damage? I am well aware of why Ike's surge was so high, because of what you stated. It rated very high on the .I.K.E scale.
