FORECAST
TROPICAL MOISTURE THIS WEEK
A good swath of tropical moisture will feed in from the Gulf by midweek. This should enhance rain chances a bit. Still, any development will be spotty, meaning not all of us will get rain. For those who do see a downpour, heavy rainfall can be expected with up to 1″ within any downpour. Severe weather is not anticipated.
Isolated to widely separated downpours possible daily through the weekend. More than anything, just tropical rain with some lightning and thunder. The odds of severe storms is very low. (Copyright 2024 by KSAT - All rights reserved.)
HURRICANE SEASON
Today officially marks the start of hurricane season. Currently, the Atlantic basin is quiet. Climatology tells us that the Gulf and northern Caribbean are favored areas for development this time of year.
