Tropical Storm Erin was the second tropical cyclone to make landfall in the United States in the 2007 Atlantic hurricane season. The fifth named storm of the season, it formed in the Gulf of Mexico on August 14 from a persistent area of convection. It attained tropical storm status the next day, and on August 16 Erin made landfall near Lamar, Texas and persisted over land across Texas before moving northward into Oklahoma. The storm resulted in at least 16 fatalities and worsened an already-severe flooding issue in Texas.

Meteorological history

On August 9, an area of convection developed just south of Jamaica in association with a trough of low pressure.cite web|author=Beven|year=2007|title=August 9 Tropical Weather Outlook|publisher=National Hurricane Center|accessdate=2007-08-14|url=] The system tracked west-northwestward, and by August 10 consisted of a broad surface trough with minimal shower activity.cite web|author=Beven|year=2007|title=August 10 Tropical Weather Outlook|publisher=National Hurricane Center|accessdate=2007-08-14|url=] Convection increased on August 11,cite web|author=Rhome|year=2007|title=August 11 Tropical Weather Outlook|publisher=National Hurricane Center|accessdate=2007-08-14|url=] and by August 12 the interaction between a tropical wave and an upper-level low in the area resulted in a large area of disorganized thunderstorms extending from the western Caribbean Sea into the central Bahamas.cite web|author=Blake|year=2007|title=August 12 Tropical Weather Outlook|publisher=National Hurricane Center|accessdate=2007-08-14|url=] Upper-level winds gradually became more beneficial for development, and on August 13 a broad low pressure area formed about 90 miles (145 km) north-northeast of Cancún, Quintana Roo.cite web|author=Knabb/Blake|year=2007|title=August 13 Tropical Weather Outlook|publisher=National Hurricane Center|accessdate=2007-08-14|url=] Late on August 14, a Hurricane Hunters flight into the system reported a small circulation center, but at the time was not well-defined enough to result in the initiation of tropical cyclone advisories. However, deep convection was maintained near the increasingly organizing center, and at 0300 UTC on August 15 the National Hurricane Center classified it as Tropical Depression Five about 425 miles (685 km) southeast of Brownsville, Texas.cite web|author=Franklin|year=2007|title=Tropical Depression Five Discussion One|publisher=National Hurricane Center|accessdate=2007-08-14|url=]

In the overnight hours after formation, the storm was disorganized with a ragged and ill-defined center of circulation. Located to the south of a mid to upper-level ridge over the southern United States, the system tracked to the west-northwest through an environment conducive for further strengthening; an upper-level anticyclone developed over the central Gulf of Mexico, and sea surface temperatures along its track were warm.cite web|author=Rhome|year=2007|title=Tropical Depression Five Discussion Two|publisher=National Hurricane Center|accessdate=2007-08-15|url=] The cloud pattern became better organized, maintaining a large area of convection with curved rainbands and well-established outflow.cite web|author=Avila|year=2007|title=Tropical Depression Five Discussion Three|publisher=National Hurricane Center|accessdate=2007-08-15|url=] Based on reports from Hurricane Hunters, the National Hurricane Center upgraded the depression to Tropical Storm Erin at 1530 UTC on August 13 about 250 miles (400 km) east of Brownsville, Texas.cite web|author=Avila|year=2007|title=Tropical Storm Erin Special Advisory 4|publisher=National Hurricane Center|accessdate=2007-08-15|url=] As it continued northwestward, Erin remained disorganized and failed to strengthen beyond minimal tropical storm status.cite web|author=Rhome/Beven|year=2007|title=Tropical Storm Erin Discussion Six|publisher=National Hurricane Center|accessdate=2007-08-16|url=] At 1200 UTC on August 16 the cyclone made landfall near Lamar, Texas as it weakened to tropical depression status.cite web|author=Avila|year=2007|title=Tropical Storm Erin Intermediate Advisory 7a|publisher=National Hurricane Center|accessdate=2007-08-16|url=] Three hours later, the National Hurricane Center ceased issuing advisories on Erin as warning responsibility was transferred to the Hydrometeorological Prediction Center.cite web|author=Avila|year=2007|title=Tropical Depression Erin Discussion Eight|publisher=National Hurricane Center|accessdate=2007-08-16|url=]

Drifting northwestward through Texas, Tropical Depression Erin maintained an area of convection near the center, with its widespread but scattered rainbands dropping moderate to heavy precipitation. By August 17, the winds decreased to 20 mph (30 km/h),cite web|author=Kocin|year=2007|title=Tropical Depression Erin Public Advisory Thirteen|accessdate=2007-08-19|url=] with higher gusts. The system turned to the north-northeast on August 18, while heavy bands of thunderstorms continued to rotate around the center of Erin.cite web|author=Kocin|year=2007|title=Tropical Depression Erin Public Advisory Fourteen|accessdate=2007-08-19|url=] Early on August 19 after entering Oklahoma, the remnants of Erin suddenly re-intensified to maximum sustained winds of 60 mph (95 km/h) a short distance west of Oklahoma City.cite web|author=.cite web|author=Kocin|year=2007|title=Remnants of Erin Public Advisory Twenty-Two|publisher=Hydrometeorological Prediction Center|accessdate=2007-08-19|url=] Its remnant mid-level circulation then moved eastward across Missouri, Kentucky, and Virginia before losing identity as it moved out into the Atlantic Ocean.


Immediately upon becoming a tropical cyclone, the National Hurricane Center issued a tropical storm watch from Freeport, Texas to the United States/Mexico border; at the same time, the government of Mexico issued a tropical storm watch southward to Rio San Fernando.cite web|author=Franklin|year=2007|title=Tropical Depression Five Public Advisory One|publisher=National Hurricane Center|accessdate=2007-08-14|url=] Shortly before attaining tropical storm status, the watch in Texas was upgraded to a tropical storm warning.cite web|author=Avila|year=2007|title=Tropical Depression Five Public Advisory Three|publisher=National Hurricane Center|accessdate=2007-08-15|url=] Late on August 15, the warning was extended to San Luis Pass, while the watch in Mexico was discontinued.cite web|author=Avila|year=2007|title=Tropical Storm Erin Public Advisory Five|publisher=National Hurricane Center|accessdate=2007-08-15|url=] As Erin made landfall, the warning was canceled, and several flood watches and warnings were issued for counties across southeastern Texas.cite web|author=Kocin|year=2007|title=Public Advisory Number 9 for Tropical Depression Erin|publisher=Hydrometeorological Prediction Center|accessdate=2007-08-16|url=] Upon moving into Oklahoma, flood and flash flood warnings were issued for several counties.

By midday on August 15, rainbands with gusty winds began affecting the Texas coastline. As it moved ashore, the storm produced heavy rainfall near and to the or northeast of its path, reaching 11.02 inches (280 mm) at a station in Lockwood.

In Clear Lake City, heavy rainfall collapsed a portion of a grocery store roof, killing two workers. The precipitation caused moderate flooding across eastern portions of Harris County; over 400 homes and 40 businesses were flooded. Flooding across the Greater Houston area briefly halted the METRORail and closed several state roads. One person drowned after driving into a retention pond.

Although its surface circulation had dissipated, its circulation aloft remained intact and led to a burst of rainfall early on August 20.
