"In the last days of August 2017, a miracle happened. A category 4 hurricane named Harvey battered Texas and Louisiana, but mostly Texas. It came onshore, with ferocious winds and rain, around Corpus Cristi, itâs eye-wall made it as far north as Cuero, before being pushed back to the coast by a prevailing high pressure system. It stayed for days. Itâs winds destroyed buildings, itâs storm surge inundated everything within it. On itâs eastern side, the wet side, the rains fell. And fell. And fell. All-told, 50 inches of rain fell over huge swaths of Texas over a period of about 3 days. This part of Texas is flat, water does not run off fast. The accumulation of water was all there at the same time. It was said to be an â800 year stormâ, meaning a storm this intense should happen about once every 800 years."
