Hold onto your hats – or better yet, your roof shingles – because Tropical Storm Francine is aiming for the U.S. coast. As of early Tuesday, the storm was brewing in the Gulf of Mexico with wind speeds already clocking in at a fierce 65 miles per hour, according to the National Hurricane Center.

And those winds aren’t just breezy – they’re downright destructive. With sustained winds like these, you’re looking at a very serious situation. Winds that hit 58 miles per hour – which Francine has already surpassed – can tear through tree limbs and send roof shingles flying through the air.

Anything stronger, and you’re staring down hurricane-force winds, starting at a brutal 74 miles per hour. So when and where will Francine make her grand (and uninvited) entrance? Here’s what we know:

• Port Isabel, Texas is bracing for impact as early as 9 a.m. today, with a more likely storm surge around 11 a.m.
• Galveston, Texas can expect Francine to come knocking by 7 p.m., but she might decide to wait until the early hours of Wednesday around 2 a.m.
