Dangerous Hurricane Jova headed for Mexico
In the Eastern Pacific off the coast of Mexico, Hurricane Jova continues to slowly intensify. Recent satellite loops show the hurricane has developed a prominent eye, and low level spiral bands have become more organized. A hurricane hunter aircraft is scheduled to arrive at Jova near 11 am PDT today. The computer models have come into excellent agreement on the track of Jova, with storm expected to hit just west of Manzanillo. The big unknown is how intense Jova will be at landfall. Jova is under light wind shear of 5 - 10 knots, and shear is predicted to stay in the low to moderate range between now and landfall. Ocean temperatures are warm, 28 - 29°C, but the warm waters do not extend to great depth, limiting Jova's potential for rapid intensification. The upper atmosphere is also not cold enough to give Jova the kind of instability typically needed for rapid intensification. Nonetheless, both the GFDL and HWRF models predict Jova will intensify into a major Category 3 and Category 4 hurricane, respectively, before landfall on Tuesday on the Mexican coast. Regardless of Jova's strength at landfall, the storm will bring very heavy rains to the Mexican coast capable of causing dangerous flash floods and mudslides, beginning on Monday.
