    Caribbean, Gulf May Yield More Tropical Systems This Week

    By 650x366_09171806_screen-shot-2013-09-17-at-2

    Texas, South Central U.S.

    Rain without a powerful tropical system would be a good thing for much of Texas, Louisiana, Arkansas and Oklahoma.

    According to Hurricane Expert Dan Kottlowski, "One system is likely to take a slow drift toward the west-northwest from the Caribbean, across the Yucatan Peninsula and into the southwestern Gulf this week."


    While there is a chance that this system slowly develops, the most important impact worth monitoring is the rainfall it produces and where that rainfall will go.

    Carrillo Puerto in the Mexico state of Quintana Roo, located in the Yucatan Peninsula, received 4.22 inches of rain during the 24-hour period ending Tuesday morning.

    Even if the system fails to develop, a significant amount of moisture is likely to drift toward northeastern Mexico initially.

    This new rain on top of what Ingrid delivers could bring a new wave of flooding problems to part of northeastern Mexico or make existing flooding problems worse.


    This time, there is also the potential for a large amount of moisture being drawn farther north into Texas and the South Central states in general starting Thursday and continuing into the weekend.

    While the pattern will bring a risk of flash and urban flooding problems, enough rain could fall to impact or break drought conditions.

    A system dropping slowly southeastward from the central and northern Rockies may help to draw up this moisture late this week into the coming weekend.

    Intense rainfall from Ingrid has been focused over Mexico with lesser rounds of showers and thunderstorms only affecting areas as far north as South Texas.

    San Antonio and Houston have received only about one-third of their normal rainfall since June 1. Meanwhile, Oklahoma City, Okla., and Dallas have received only about 20 percent of their normal rainfall in the past month. Little Rock, Ark., has received only 1 percent of its normal rain in the past 30 days.

    Some of this heavy rain could also fall on parts of New Mexico, which has also been experiencing flash flooding over the past week not associated with Ingrid.

    Albuquerque, N.M., has received nearly three times its normal rainfall of about 1 inch since Sept. 1. During the same period Truth of Consequences, N.M., has received four times its normal rainfall of 1.50 inches.

    South Florida

    The same broad area of disturbed weather could generate a couple more disturbances later in the month. Steering winds over the region could be such to drive some of that moisture toward the northeast across Cuba, the Bahamas and perhaps South Florida.

    The area from Key West to Miami and West Palm Beach have the potential to receive several inches of rain through midweek.

    "An area of disturbed weather over the southeastern Gulf of Mexico is already pumping moisture into South Florida this week. Frequent showers and thunderstorms are in store from the Keys to Miami, Homestead, Fort Lauderdale, West Palm Beach and Naples," Kottlowski said.

    The entire area from the northwest Caribbean to the southern Gulf of Mexico, the Florida Straits and waters just east of Florida will be watched closely for tropical development this week and the next.


    "Disruptive winds and dry air will tend to limit development farther east over the tropical Atlantic to the coast of Africa," according to Kottlowski, "However, conditions will remain more favorable over the southwestern part of the Atlantic basin during the next couple of weeks."

    Elsewhere in the Atlantic, Humberto has regained tropical storm status in the middle of the basin but is not expected to directly impact land areas through Friday.
