Early in the week, as moisture from the Gulf of
Mexico streamed northward, a slow-moving frontal
system provided the focus for numerous storms
over the Southern Plains. The result was extensive
flooding over parts of Texas and Oklahoma. On
Monday (18 June 2007), six flood-related deaths
were reported in northern Texas as storms dumped
up to 8 inches of rain in the area. On Tuesday,
additional storms dumped heavy rains over parts of
northwestern Oklahoma, forcing several road
closures. The TRMM-based, near-real time
Multi-satellite Precipitation Analysis (MPA) at the
NASA Goddard Space Flight Center is used to
monitor rainfall over the global tropics. MPA rainfall
totals are shown in the image above for the period
14 to 20 June 2007. The MPA analysis indicates that
during this time over 200 mm (~8 inches, red area) of
rain fell in northern Texas just south of the
Oklahoma border. A much broader area of at least
150 to 200 mm (~6 to 8 inches) of rain covers most
of northwest Oklahoma. Click here to see TRMM
web pages that show areas of high flood potential
anywhere on earth.
TRMM is a joint mission between NASA and the Japanese space agency JAXA.
