rain from hurricane Harvey--

Flash flood watches expanded as far east as New Orleans, where the Weather Service said 5 to 10 inches were possible through Thursday. Over an inch had fallen through Monday afternoon, pushing the summer’s rainfall total to the highest mark on record.

Through Monday evening, locations near Houston in Harris County had seen up to 37 inches of rain, with a county average of 33 inches. Isolated areas to the northeast had received up to 40 inches.

According to the National Weather Service, the forecast of more than a foot of additional rainfall in the Houston area “would have devastating consequences on the continuing rescue and recovery efforts.”

Some areas in Southeast Texas could see storm rainfall totals exceeding 50 inches, which would break state records. An analysis by Eric Berger, a scientist who pens Houston weather blog, concluded Harvey is “almost certainly the biggest U.S. flood-producing storm” on record.




The astronomical rain totals had pushed river levels in Southeast Texas near and beyond record levels.

The Weather Service office serving Houston described the rain amounts so far “ unfathomable.” The 16.07 inches that fell on Houston’s George Bush Airport on Sunday marks the single wettest day in Houston history, making up nearly a third of the 49.77 inches the city sees in an average year. More than two feet fell over the weekend, a record two-day amount. Over the Houston metro area, so much rain would be expected to happen between just one time every 500 to 1,000 years.

The August rainfall in Houston, largely from Harvey, shattered its record for any month by a whopping 13.47 inches.

This flood disaster has easily surpassed the havoc wrought by the landmark Tropical Storm Allison in 2001, the Weather Service said.

Economic damage in the many billions of dollars is inevitable, according to economists and reinsurers.
