Two trop­i­cal storms gath­ered strength off Mex­i­co’s Pa­cif­ic Coast Mon­day, with one fore­cast to be­come a hur­ri­cane lat­er in the day, fore­cast­ers warned.

Trop­i­cal Storm Bar­bara was about 185 miles (295 kilo­me­tres) south­west of Man­zanil­lo, Mex­i­co ear­ly on Mon­day, with max­i­mum sus­tained winds of 70 mph (110 kph), ac­cord­ing to the U.S. Na­tion­al Hur­ri­cane Cen­tre in Mi­a­mi.

Bar­bara is ex­pect­ed to con­tin­ue mov­ing to­ward the west-north­west near 12 mph for the next cou­ple of days. It will reach hur­ri­cane strength lat­er on Mon­day but should be­gin weak­en­ing by Tues­day, the NHC said.

The storm may bring to­tal rain­fall of 2 to 4 inch­es (51 to 101 mil­lime­tres) to coastal ar­eas of Guer­rero, Mi­choa­can, Col­i­ma and Jalis­co states, with the pos­si­bil­i­ty of lo­calised flood­ing on Mon­day.

The NHC said swells from Bar­bara were like­ly to form life-threat­en­ing surf and rip cur­rent con­di­tions along the south­west­ern Mex­i­can coast, with gusty winds like­ly.

An­oth­er trop­i­cal storm, Cosme, strength­ened slight­ly Mon­day but re­mained well off the coast of Mex­i­co, about 630 miles (1,015 kilo­me­tres) south-south­west of the tip of Ba­ja Cal­i­for­nia, the NHC said.

At 2 a.m. lo­cal time it had max­i­mum sus­tained winds of 50 mph and was mov­ing west-north­west at 9 mph. Cosme is ex­pect­ed to reach near-hur­ri­cane strength on Mon­day be­fore turn­ing to the north­east and pick­ing up speed Tues­day in­to Wednes­day.
