Hurricane Beatriz slams into Mexico; heavy rains, tornadoes hit the Midwest
Posted by: Dr. Jeff Masters, 2:34 PM GMT on June 21, 2011 +7
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.

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.

I have 2 45 gal barrels that I bought from Lowes for about 40 a piece. They hook up directly to your downspouts, complete with overflow control. As for the "shingle gravel" the lids are removable and you just hose them out. Also have a spigot to hook a garden hose to.

Not at all, went from being 2x the monthly average since January to about 1/4 of the average this month (even though this is suppose to be the month with the max rainfall amount). Maybe this storm will fix that.


Well, it might not rain that hard for that long, but if I am correct, you could pick up more than an inch in 30 minutes to an hour with moisture as high as it is.

Here in Florida, 2 to 3 inch per hour rainfall rates are common. During the wet season when we get tropical waves combining with sea breeze convergence, the extremely moist air can produce 5 inch per hour rain rates or more. But these periods of extreme rainfall are usually short lived because we usually don't have the dynamics in the air to support storms hanging around very long so we end up with in actuality, a 15 to 30 minute down pour dumping rain in the 1 to 3 inch range.

We had 15 inches in 3 hours a few years back, that was scary, thankfully drainage is good and we are close to the coast here in the Tampa Bay area so it never flooded the house, but still, that was crazy. I have seen other stuff like that before but that is rare even here.

There is some low level vorticity associated with the recent blowup of convection to the west of the BOC, but it is overland right now. Maybe this will be the start of something. Still waiting to see what is up with the large area of LLC left over from Beatriz.


Beatriz is nearing her death, there will be no re-intensification of the system. I'll believe there will be when we start seeing unicorns and pigs start flying.

The storm in the midwest is trying to grab at Beatriz a bit. Pulled some midlevel something toward the gulf, moisture maybe on the way to some drought areas.

Yea it might not even reach me, but who knows; I've had strong lines of severe weather coming and then a little gap forms making everyone else get hit but my area. Definitely would have major flooding up here if there was rainfall like Florida usually has, I think the most we got from a storm this year is 2-3 inches and even then the streets begin to backup with water. Maximum monthly average around this area (peak of the year) is only around 3.16 inches.


Yeah its amazing how that kind of rain up there makes everything beautiful and green, but the dry season here is 2.5 to 3.5 inches a month. It all depends on how the climate is adjusted to, type of foliage as well as soil. The wet season we average 7 to 10 inches a month. sometimes less during some years years, and sometimes it can be way more during others. I have seen us get 15 to 20 inches in August and September several times before since Ive lived here. But then there's last year, which was very dry, and we only had 4 to 5 inches both months, which was considered bad for us. I have seen us get a foot of rain sometimes in June, and years like this, we have only had 1 inch so far. The good news is, climate forecasts are calling for lots of rain the rest of the rain season.

The way it works in the subtropics of Florida. We either get slammed for a while with rain, or we get real dry for a while. Also, most of the days it rains, we also get lots of sun, some of our heaviest rain days we manage to squeeze out several hours of sun, hence why they call us the sunshine state. Being a weather freak and an athletic/outdoorsman, its the best Climate in the U.S. to me.

To early to really say, I've been watching the left-overs of Beatriz spin off weak circulations towards the BOC since yesterday (mostly from the adjacent monsoon inflow being to strong). Still not really sure what is going on with it though; a cold pocket of air did run into it right before it collapsed, so its difficult to predict how it will transform over the next day or two. Maybe Beatriz will acquire unicorns and flying pigs over the next few hours, otherwise the area near the BOC could have a very slight chance of becoming what the models are sensing (but if Beatriz redevelops then I would say a 0% chance).

Beatriz is dead, I pulled her life support plug out last night before going to bed.
