The Washington Post: Harvey forecast to slam Texas coast as major hurricane with ‘devastating’ flood potential https://www.washingtonpost.com/news/capital-weather-gang/wp/2017/08/24/rapidly-strengthening-harvey-forecast-to-slam-east-texas-as-major-hurricane-and-stall

Bob Henson from Wunderground: A Hurricane Warning is in effect from Port Mansfield to Sargent, Texas, including the Corpus Christi area, with a Storm Surge Warning from Port Mansfield north to High Island and a Hurricane Watch southward to the Mexico border and.

Harvey poses an unusually complex, multifaceted, prolonged, and dangerous threat over the next several days to parts of South Texas, including the central TX coastline as well as locations well inland.

Localized multi-day rainfall amounts could be as much as 35″, according to the National Hurricane Center (NHC).

Union of Concerned Scientists notes on Climate and Hurricanes:
Research in this area suggests that hurricanes in the North Atlantic region have been intensifying over the past 40 years.

Since the mid-1970s, the number of hurricanes that reach Categories 4 and 5 in strength—that is, the two strongest classifications—has roughly doubled.

Measures of the potential destructiveness of hurricanes (a measure of the power of a hurricane over its entire lifetime) also show a doubling during this time period. Indices for hurricane activity based on storm surge data from tide gauges further indicate an increase in intensity.

Warm ocean temperatures are one of the key factors that strengthen hurricane development when overall conditions are conducive for their formation and growth.

Hurricanes require high humidity, relatively constant winds at different altitudes, and can occur when surface ocean temperatures exceed about 79°F (26°C).
