After Days of Agony…

The continuous rainfall in Houston…is over.

Unfortunately, Harvey remains a 45 mph tropical storm. Although its center has moved east, ending rain in Houston, the torrential rain is spreading into far SE Texas with increasing concerns in Southwest and southern Louisiana as well.

Heavy rain cause by thunderstorm activity north Harvey’s center to circulation. Far southeast TX into Southwest LA have been hard hit today with flash flooding.

Harvey is expected to make landfall on the Southwest LA Coast Wed morning. No further strengthening is expected as the system is too disorganized and in a high vertical wind shear environment to support rapid intensification (thankfully). It will move across western LA Wed-early Thurs, being heavy rain to much of the state and spreading into Arkansas.

New Record-

Today, Harvey (preliminarily) set the Continential US record for highest storm total rainfall for a tropical cyclone at 51.88 inches at Cedar Bayou in the Houston area. The previous record was Hurricane Amelia in 1978 with 48 inches (also in TX). Almost all of this rain fall in the 72 hr period with Saturday night-Sunday morning being the absolute worst with 15- 25 inches of rain in 12-15 hrs, initially the catastrophic urban flood event in Houston. One automated rain gauge which captured rainfall per min saw an equivalent rainfall rate ~12 inches/hr very briefly late Saturday night!

And additional 15-25 inches fell Sunday-Monday worsening the situation and conditions for those waiting for rescue miserable.

Storm totals ending Tuesday morning.

As of this post, 31 people are reported to have died as a result of Harvey in the US…one in Rockport who died in a house fire at the height of the storm; and 30 in the Houston area, most flood-related.
