If you’ve ever been to Indian State of Kerala and the western Ghats, you know that yesterday, with the warmth, the thick, pounding rain with cloud bases at tree-top levels, visibility a mile or two, and with little or no lightning, was a true sample of India in the summer, maybe a July day in the western Ghats.
Congratulations for having experienced India and a TRUE monsoon day without having to go anywhere1.
The totals? 4.48 inches at Our Garden on Columbus Avenue, wettest day in their 37 year record. 4.59 inches on Samaniego Peak. The largest amount I could find was at Stewart Dam by the Salt River, 4.79 inches, all in 24 h, though most of these totals fell in less than 3 h. Below a shot of the CDO wash at or near its peak at Wilds Road, the latter a “street” if I may, one that might now surpass in difficulty the Charoulou Gap for the 4-wheeler and ATV crowd judging from the way it looked yesterday.
BTW, the shots below are from a video taken by yours truly in the pounding rain as the total here in Sutherland Heights surpassed the 3 inch mark, on its way to 4.18 inches. I was the only one there, except for Jessie, who runs Our Garden, who also showed up in the pounding rain right after I did, saying, “I thought I’d find you here.” Huh.
This was twice as big and fast moving as anything I had seen in the prior seven summers, though doesn’t compare to the August 2003 flood in which the CDO wash at this location got all the the way to Lago del Oro Parkway, a hundred yards wider than this.
With yesterdays soaking wet air over us, it didn’t take much to send turrets spaceward, and it MAY have been that those car-floating rains in the Phoenix area had something to do with what happened.
A gust front moving this way was evident in the satellite and radar imagery as new echoes raced to the SE from that whopper after midnight. The gust front appeared to dissipate before getting here, but then not long after the heavy rains began, the wind came up from the north after calm conditions marked the first inch or two. And the rains intensified. Clearly, wherever that wind shift came from, it gave the clouds above us another boost, to push an already memorable rain into historic proportions by helping generated the second two inches. (I hope you logged the time of this important windshift in your weather diary yesterday.)
Here are some shots from that historic day, one that we will likely not live to see again:
OK, its pretty hard to take pictures of rain, but these two below were the best I could do, and I hope you appreciate it. I have no idea why I took 85 pictures of heavy rain; they don’t look that great in retrospect, but it was exciting to be taking them…kind of lost control.
The rest of the day was truly history, and by afternoon, things were clearing out, and by late in the day left those usual, “memorable” scenes of our mountains decked in clouds. The mountains seemed greener, washed up as it were, more than usual after good rains.
Today…..U of AZ mod run from 11 PM last night sez no rain around here today or tomorrow. With the residual moisture we have, and clouds topping Samaniego Ridge this morning, it would be hard to imagine that early on in the day, later this morning that a few huge Cumulonimbus clouds won’t arise over the Cat Mountains before the drying takes hold. So, we might see some great clouds right away, and then watch them wither as the dry air manifests itself.
In the longer term, yesterday’s 12 Z run was amazing since it had more heavy rains down the road, a week or so out, with another “Norbert” like storm traveling up the Baja coastline. Imagine! And on last evening’s run at 5 PM AST, it has it in almost an identical trajectory as Norbert. Check this out. Never have seen that before, such a replication of something fairly strange in the first place. I just saw this now, and am so excited am going to slip it here adding already to “blog excess” and “reader fatigue”:
1In the southern peninsula region of India, east of the Ghats in during the time of the SW monsoon, there are giant thunderstorms with incredible LTG, but they’re more scattered around than the “24/7” monsoon rains in the Ghats, rains that can produce up to 300 inches in a month, though averages are closer to 100.
