CONTINUING TO MONITOR THE INFLUX OF TROPICAL MOISTURE FROM INVEST
98L. WHILE THE MOST OF THE ACTIVITY HAS BEEN LOCATED OFF THE COAST,
THERE IS STILL TIME FOR THE SHOWERS AND THUNDERSTORMS TO MOVE
ASHORE. WHILE THE MAJORITY OF THE ACTIVITY SHOULD BE COMING TO AN
END TOWARDS THE END OF THE AFTERNOON AND INTO THE EARLY EVENING
HOURS, A STRAY SHOWER OR THUNDERSTORM IS STILL POSSIBLE TONIGHT.
RAINFALL ASSOCIATED WITH THESE SHOWERS AND THUNDERSTORMS COULD BE
AROUND 2 INCHES WITH SOME LOCATIONS SEEING UP 4 INCHES POSSIBLE.
A FLOOD WATCH IS STILL IN EFFECT FOR SOUTHERN HIDALGO AND CAMERON
COUNTIES THROUGH 6 PM, WHILE THE AREA OF SLIGHT RISK OF EXCESSIVE
RAINFALL HAS BEEN TRIMMED DOWN A BIT TO FOCUS ALONG THE COAST.
AS FOR THE TEMPERATURES, HIGHS ARE EXPECTED TO REMAIN MOSTLY IN THE
UPPER 90S TO LOWER TRIPLE DIGITS FOR THE AREA. THE HEAT RISK FOR THE
PERIOD IS GENERALLY IN THE MODERATE CATEGORY (LEVEL 2 OF 4), HOWEVER
THE HEAT INDICES FOR TOMORROW IN KENEDY AND WILLACY COUNTIES DO GET
OVER 111 FOR A FEW HOURS. THIS COULD POTENTIALLY MEET THE CRITERIA
FOR HEAT ADVISORY, HOWEVER CONFIDENCE IS NOT HIGH ENOUGH TO ISSUE A
HEAT ADVISORY AT THIS CURRENT TIME. AFTER, TOMORROW THE HEAT INDICES
DO TEND TO STAY UNDER 110. LOW TEMPERATURES ARE EXPECTED TO BE IN
THE 70S EACH NIGHT WITH SOME PLACES APPROACHING NEAR 80.
LASTLY, ALONG THE LOWER TEXAS COAST, A MODERATE RISK OF RIP CURRENTS
IS IN EFFECT THROUGH TOMORROW DUE TO THE INCREASED WAVES AND SWELL
FROM THE LOW PRESSURE SYSTEM.
